Odd subgraphs are odd (Asaf Ferber, UC Irvine)
On ZoomIn this talk we discuss some problems related to finding large induced subgraphs of a given graph G which satisfy some degree-constraints (for example, all degrees are odd, or all […]

Difference sets in higher dimensions (David Conlon, Cal Tech)
On ZoomLet d >= 2 be a natural number. We determine the minimum possible size of the difference set A-A in terms of |A| for any sufficiently large finite subset A […]

Questions on Symmetric Chains (Shahriar Shahriari, Pomona)
On ZoomThe set of subsets {1, 3}, {1, 3, 4}, {1, 3, 4, 6} is a symmetric chain in the partially ordered set (poset) of subsets of {1,...,6}. It is a […]

APPLIED MATH SEMINAR: Archetypal analysis by Professor Braxton Osting (University of Utah)
Archetypal analysis is an unsupervised learning method that uses a convex polytope to summarize multivariate data. For fixed k, the method finds a convex polytope with k vertices, called archetype […]

Niho’s last conjecture (Daniel Katz, Cal State Northridge)
On ZoomA power permutation of a finite field F is a permutation of F whose functional form is x -> x^d for some exponent d. Power permutations are used in cryptography, […]

Applied Math Seminar — Yunied Puig de Dios (CMC)
Emmy Noether Room, Estella 1021, Pomona College, 610 N. College Ave., Claremont, CA, United StatesTitle: Modern techniques to approach the invariant subspace problem Abstract: The invariant subspace problem is by far one of the most important problems in operator theory. It has been open for more than half a century, and there are many significant contributions with a huge variety of techniques, making this challenging problem so interesting; however […]

Frame coherence and nearly orthogonal lattices (Lenny Fukshansky, CMC)
On ZoomA frame in a Euclidean space is a spanning set, which can be overdetermined. Large frames are used for redundant signal transmission, which allows for error correction. An important parameter of frames is coherence, which is maximal absolute value of the cosine of the angle between two frame vectors: the smaller it is, the closer […]
