Local operators in supersymmetric conformal field theory are in representations of the super- conformal group. In this talk, I will briefly review this representation theory and apply it to shed light on some basic questions such as: Are there (N,0) superconformal field theories? Do the (2,0) theories have continuous parameters or global symmetries? Why is the (2,0) theory on a circle described by 5d Super-Yang-Mills? How can we understand the RG flow of the (2,0) theory on its moduli space?

We give a simultaneous generalization of exact categories and triangulated categories, which is suitable for considering cotorsion pairs, and which we call extriangulated categories. Extension-closed, full subcategories of triangulated categories are examples of extriangulated categories. We give a bijective correspondence between some pairs of cotorsion pairs which we call Hovey twin cotorsion pairs, and admissible model structures. As a consequence, these model structures relate certain localizations with certain ideal quotients, via the homotopy category which can be given a triangulated structure. This gives a natural framework to formulate reduction and mutation of cotorsion pairs, applicable to both exact categories and triangulated categories. These results can be thought of as arguments towards the view that extriangulated categories are a convenient setup for writing down proofs which apply to both exact categories and (extension-closed subcategories of) triangulated categories.

Let T be a triangulated category. A basic question is the classification of the triangulated subcategories of T. The interest in this question stemmed from the work of Hopkins who connected it to the Telescope conjecture in algebraic topology. Over the last two decades, spurred by work of Neeman, there has been interest in this from the perspective of algebraic geometry. Most recently, this has been considered by Antieau, Stevenson, Balmer-Favi and Dubey-Mallick. I will discuss some recent work with Rydh that allows us to classify subcategories in the equivariant setting and, more generally, for stacks.

In this talk I will construct and analyze a model of cell receptor aggregation. We study the impact of density dependent diffusion on aggregate formation in a one-dimensional domain. Critical values of receptor diffusion and receptor activation are found and compared with numerical simulations. In the case of receptor activation the analytical results agree very well with the numerical calculations. Finally, we consider our model in higher dimensional domains. In this case our analysis is primarily numerical.

Haruzo Hida has constructed a 3-variable Rankin Helberg \(p\)-adic \(L\)-function.
Two of its variables are "weight" variables and one of its variables is the "cyclotomic"
variable. Samit Dasgupta has factored a certain restriction of this 3-variable \(p\)-adic
\(L\)-function (when the two weight variables are set equal to each other) into a product
of a 2-variable \(p\)-adic \(L\)-function (related to the adjoint representation of a Hida family)
and the Kubota-Leopoldt \(p\)-adic \(L\)-function. We prove the corresponding result involving
Selmer groups that is predicted by the main conjectures. A key technical input is studying
the (height one) specialization of Selmer groups.

I will report on recent joint work with Antonio Lei on the anticyclotomic Iwasawa
theory of the base change of an elliptic modular form to an imaginary quadratic field
\(K\) in which the prime \(p\) splits. We treat both the definite and indefinite cases in
both \(p\)-ordinary and non-\(p\)-ordinary situations. One of our main results is an
equality (up to powers of \(p\)) that is predicted by the main conjectures in the definite
\(p\)-ordinary set up and a \(\Lambda\)-adic Birch and Swinnerton-Dyer formula in the
indefinite case.

Abstract: Process modeling and simulation is a key enabling technology for chemical engineers to develop and design innovative and safe chemical processes. The underlying molecular thermodynamic models provide the scientific foundation essential for all process calculations involving thermophysical properties, heat and mass transfer, chemical reactions, phase and chemical equilibria, etc. Indeed, tremendous past accomplishments and recent advances in molecular thermodynamics have served chemical engineers well and contributed to the wide acceptance of process modeling and simulation especially in oil and gas industry and petrochemical industry. A prominent recent example is the development of a novel molecular thermodynamic model for chemical absorption of CO2 with a proprietary organic amine solution and the application of the model in the development, design, and optimization of the 1st commercial scale CO2 capture unit operated by Saskpower. However, many unsolved problems remain while new challenges emerge as chemical engineers explore new opportunities and frontiers such as carbon capture and sequestration, energy storage, saline water remediation, nuclear waste disposal, etc. This talk highlights several high impact research opportunities in the pursuit of sustainable energy. Specifically, we present new advances in molecular thermodynamics in support of modeling and simulation for high salinity produced water treatment processes in oil and gas production, defense nuclear waste treatment processes, noble metal extraction from recycled electronics, asphaltene aggregation in petroleum processing, and hybrid sulfur (HyS) cycle for hydrogen production.

We study the problem of determining whether or not a
discrete distribution has a given property from a small number of
samples. We present a new technique in this field that operates by
reducing many such problems in a black box way to a simple L^2 tester.
We show how this new technique can recover simple proofs of several
known, optimal results and how it can be extended to provide optimal
solutions to a number of previously unsolved problems.

Given a simplicial complex \(\Delta\subset \mathbb R^d\), let \(C^r_k(\Delta)\) denote the vector space of piecewise polynomial functions (algebraic splines) of degree \(\le k\) and smoothness \(r\). A major problem is to determine the dimension (and construct bases) of these vector spaces. Pioneering work by Billera, Rose, Schenck, and others gave upper and lower bounds using homological methods.
The ring of continuous splines \(C^0(\Delta)=C^0_k(\Delta)\) is (essentially) equal to the face ring, or Stanley--Reisner ring, of \(\Delta\) and has the property that its geometric realization describes $\Delta$. More precisely, the part of \({\rm Spec}(C^0(\Delta))$\) lying in a certain hyperplane and having nonnegative coordinates is ``equal'' to \(\Delta\). Here we shall consider the \emph{generalized Stanley--Reisner rings} \(C^r(\Delta):=\oplus_k C^r_k(\Delta)\subset C^0(\Delta)\). We present a conjectural description of \({\rm Spec}(C^r(\Delta))\) generalizing the one for \(r=0\). To illustrate the conjecture, some very simple examples will be given.

We study the space of geometrically continuous splines, or piecewise polynomial functions, on topological surfaces. These surfaces consist of a collection of rectangular and triangular patches together with gluing data that identifies pairs of polygonal edges. A spline is said to be G1-geometrically continuous on a topological surface if they are C1-continoous functions across the edges after the composition by a transition map.
In the talk we will describe the required compatibility conditions on the transition maps so that the C1-smoothness is achieved, and give a formula for a lower bound on the dimension of the G1 spline space.
In particular, we will show that this lower bound gives the exact dimension of the space for a sufficiently large degree of the polynomials pieces. We will also present some examples to illustrate the construction of basis functions for splines of small degree on particular topological surfaces.

In this talk we will give a panorama about the state of the problem of classification of weakly integral modular categories at the moment. We will present some of the known results for low rank and for specific dimensions, like 4m and 8m, with m a square-free odd integer. We will also explain some of the techniques that we found useful to push further the classification.

Many survival studies have error-contaminated covariates, which may lack a gold standard of measurement. Furthermore, the error distribution can depend on the true covariates but the dependence structure is typically diﬃcult to quantify; heteroscedasticity is a common manifestation. In this talk, we suggest an additive measurement error model in this circumstance, and develop a functional modeling method for Cox regression when an instrumental variable is available. The estimated regression coeﬃcients are consistent and asymptotically normal. Preliminary numerical studies, including simulations, will be provided.
