Title: A crash course in Bornologies Abstract: By a bornology on a nonempty set X, we mean a family of subsets that contains the singletons, that is stable under finite unions, and that is stable under taking subsets. The prototype for a bornology is the so-called metric bornology: the family of metrically bounded subsets of […]
A modification of the cellular resolution of the diagonal given by Bayer-Popescu-Sturmfels gives a virtual resolution of the diagonal for smooth projective toric varieties and toric Deligne-Mumford stacks which are […]
Title: A polyhedral view of refined q-t Catalan numbers Speaker: Max Hlavacek Assistant Professor of Mathematics and Statistics department, Pomona College, Claremont Abstract: Many problems in algebraic combinatorics have geometric objects lurking in […]
Title: How well do neurons, humans, and artificial neural networks predict? Abstract: Sensory prediction is thought to be vital to organisms, but few studies have tested how well organisms and […]
Around 20 years ago, physicists Michael Faux and Jim Gates invented Adinkras as a way to better understand Supersymmetry. These are bipartite graphs whose vertices represent bosons and fermions and […]
We welcome all undergraduate/graduate students and faculty to attend topology seminar! Speaker: Reginald Anderson (CMC) Title: Presentations of derived categories Abstract: A modification of the cellular resolution of the diagonal […]
We will see you all next week!
Title: What can chicken McNuggets tell us about symmetric functions, positive polynomials, random norms, and AF algebras? Abstract: Numerical semigroups are combinatorial objects that lead to deep and subtle questions. With tools from complex, harmonic, and functional analysis, probability theory, algebraic combinatorics, and computer-aided design, we answer virtually all asymptotic questions about factorization lengths in […]
Title: How to use coins to make a 7-sided die Abstract: Certain dice are easier to make than others. There is the standard 6-sided die, but 4-sided, 8-sided, 10-sided, 12-sided, and 20-sided are also very common. What isn't so common is a 7-sided die. Here Dr. Mark Huber from Claremont McKenna College will talk about […]
Title: TBD Abstract: TBD
I will introduce two general problems and explain how they surprisingly connect with each other and with other aspects of mathematics (for a glimpse, Sato—Tate, hypergeometric functions, moduli spaces of sheaves, Catalan numbers, Hall polynomials, etc.). The first problem is to count finite-field points on so called "varieties of matrix points''. They are created from […]
Speaker: Anne Cawley, Associate Professor of Mathematics and Statistics, Cal Poly Pomona, CA Title: What Happens When Our Perspectives Don’t Align with the Math? Abstract: Many people often share that they like math because there is “one right answer” and is an objective field. Once they find the answer, they are done with a problem. […]
