Skein algebra of a punctured surface (Helen Wong, CMC)
The Kauffman bracket skein algebra of a surface is at once related to quantum topology and to hyperbolic geometry. In this talk, we consider a generalization of the skein algebra […]

What can chicken nuggets tell us about symmetric functions, positive polynomials, random norms, and AF algebras? (Stephan Garcia, Pomona)
Roberts North 102, CMCA simple question about chicken nuggets connects everything from analysis and combinatorics to probability theory and computer-aided design. With tools from complex, harmonic, and functional analysis, probability theory, algebraic combinatorics, […]

On the Cox ring of a weighted projective plane blown-up at a point (Javier Gonzalez Anaya, HMC)
Roberts North 102, CMCThe Cox ring of a projective variety is the ring of all its meromorphic functions, together with a grading of geometric origin. Determining whether this ring is finitely generated is […]

f^*-vectors of lattice polytopes (Max Hlavacek, Pomona College)
Roberts North 102, CMCThe Ehrhart polynomial of a lattice polytope P counts the number of integer points in the nth integral dilate of P. The f^* -vector of P, introduced by Felix Breuer […]

Frobenius coin-exchange generating functions (Matthias Beck, San Francisco State University)
Roberts North 102, CMCWe study variants of the Frobenius coin-exchange problem: Given n positive relatively prime parameters, what is the largest integer that cannot be represented as a nonnegative integral linear combination of the given integers? This problem and its siblings can be understood through generating functions with 0/1 coefficients according to whether or not an integer is representable. […]

Deep hole lattices and isogenies of elliptic curves (Lenny Fukshansky, CMC)
Roberts North 102, CMCFor a lattice L in the plane, we define the affiliated deep hole lattice H(L) to be spanned by a shortest vector of L and the furthest removed vector from […]

Cellular resolutions of the diagonal and exceptional collections for toric D-M stacks (Reginald Anderson, CMC)
Roberts North 102, CMCBeilinson gave a resolution of the diagonal for complex projective space, which gives a strong, full exceptional collection of line bundles as a generating set for the derived category of […]

Chromatic numbers of abelian Cayley graphs (Michael Krebs, Cal State LA)
Roberts North 102, CMCA classic problem in graph theory is to find the chromatic number of a given graph: that is, to find the smallest number of colors needed to assign every vertex […]

Biquandle power brackets (Sam Nelson, CMC)
Roberts North 102, CMCBiquandle brackets are skein invariants of biquandle-colored knots, with skein coefficients that are functions of the colors at a crossing. Biquandle power brackets take this idea a step further with […]

Numerical semigroups, minimal presentations, and posets (Chris O’Neill, SDSU)
Roberts North 102, CMCA numerical semigroup is a subset S of the natural numbers that is closed under addition. One of the primary attributes of interest in commutative algebra are the relations (or […]

Quantum money from Brandt operators (Shahed Sharif, CSU San Marcos)
Roberts North 102, CMCPublic key quantum money is a replacement for paper money which has cryptographic guarantees against counterfeiting. We propose a new idea for public key quantum money. In the abstract sense, […]
