m-Koszul AS-regular algebras and twisted superpotentials
Banff International Research Station for Mathematical Innovation and Discovery
Mori, Izuru — Faculty Author affiliation: Shizuoka University Unreviewed Non UBC This talk is based on a joint work with S. P. Smith. AS-regular algebras is an important class of algebras to study in noncommutative algebraic geometry. If S is an m-Koszul AS-regular algebra, then it was observed by several people that S is determined by a twisted superpotential. In this talk, we will see that such a twisted superpotential is uniquely determined by S up to non-zero scalar multiples and plays a crucial role in studying S. In particular, we will see in this talk that, using the twisted superpotential w_S associated to S, we can compute (1) the Nakayama automorphism of S, (2) a graded algebra automorphism of S, and (3) the homological determinant of a graded algebra automorphism of S (which is an essential ingredient for invariant theory of an AS-regular algebra). If time permits, we will present some applications to 3-dimensional noetherian Calabi-Yau algebras (which is partially based on a joint work with K. Ueyama). http://creativecommons.org/licenses/by-nc-nd/4.0/

On periodic traveling waves of the Camassa-Holm equation
Banff International Research Station for Mathematical Innovation and Discovery
Geyer, Anna — In this talk we are concerned with the wave length $\lambda$ of smooth periodic traveling wave solutions of the Camassa-Holm equation. The set of these solutions can be parametrized using the wave height $a$. Our main result establishes monotonicity properties of the map $a\mapsto \lambda(a)$ i.e., the wave length as a function of the wave height. We obtain the explicit bifurcation values, in terms of the parameters associated with the equation, which distinguish between the two possible qualitative behaviours of $\lambda(a)$, namely monotonicity and unimodality. The key point is to relate $\lambda(a)$ to the period function of a planar differential system with a quadratic-like first integral, and to apply a criterion which bounds the number of critical periods for this type of systems.

Alternating knots satisfy the L-space knot conjecture
Banff International Research Station for Mathematical Innovation and Discovery
Roberts, Rachel — I will describe a construction of (codimension one) co-oriented taut foliations (CTFs) of 3-manifolds. It follows from this construction that if K is a composite, alternating, or Montesinos knot, then the L-space conjecture of Ozsvath and Szabo holds for any 3-manifold obtained by Dehn surgery along K. I will focus on the alternating knot case. This work is joint with Charles Delman.

1.Turn on the map filter by clicking the “Limit by map area” toggle.
2.Move the map to display your area of interest. Holding the shift key and clicking to draw a box allows for zooming in on a specific area. Search results change as the map moves.
3.Access a record by clicking on an item in the search results or by clicking on a location pin and the linked record title.
Note: Clusters are intended to provide a visual preview of data location. Because there is a maximum of 1000 records displayed on the map, they may not be a completely accurate reflection of the total number of search results.
