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 […]

Using Stitching for faster sampling (Prof. Mark Huber)
Title: Using Stitching for faster sampling Speaker: Mark Huber, Department of Mathematics, Claremont McKenna College Abstract: Point processes are used to model location data, such as the locations of trees in a forest, […]
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, […]
Exploiting metric structure for more accurate classification (Prof. Mike Izbicki)
Zoom meeting , United StatesTitle: Exploiting metric structure for more accurate classification Speaker: Mike Izbicki, Department of Mathematical Sciences, Claremont McKenna College Abstract: Classification problems often have many semantically similar classes. For example, the famous ImageNet dataset […]
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 […]
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 […]

On ZoomOne of the most important axioms in analyzing voting systems is that of "neutrality", which stipulates that the system should treat all candidates symmetrically. Even though this doesn't always directly […]
On Invariants for Surface-Links in Entropic Magmas via Marked Graph Diagrams (Seonmi Choi, Kyungpook Natl U, Korea)
ZoomM. Niebrzydowski and J. H. Przytycki defined a Kauffman bracket magma and constructed the invariant P of framed links in 3-space. The invariant is closely related to the Kauffman bracket […]
