"The Sceptical Mathematician: How John Wallis Saved Mathematics for the Royal Society." Abstract: The members of the “Invisible College” and the early Royal Society championed an experimental approach to the study of nature as the proper path to the advancement of knowledge and the preservation of civic peace. Mathematics, while admired, was also viewed with suspicion, […]

Title: Towards Understanding the Success of First Order Methods in Training Mildly Overparameterized Networks Abstract: For most problems of interest the loss landscape of a neural network is non-convex and contains a plethora of spurious critical points. Despite this first order methods such as SGD and Adam are in practice remarkably successful at finding optimal, […]
Biquandle power brackets (Sam Nelson, CMC)
Biquandle power brackets (Sam Nelson, CMC)
Biquandle 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 state component values that also depend on biquandle colors. This is joint work with Neslihan Gügümcü (IYTE).

Title: Cellular resolutions of the diagonal and exceptional collections for toric Deligne-Mumford stacks Abstract: Beilinson gave a resolution of the diagonal for complex projective space which yields a strong, full exceptional collection of line bundles. Bayer-Popescu-Sturmfels generalized Beilinson's result to a cellular resolution of the diagonal for what they called "unimodular" toric varieties (a more restrictive […]
p-Norm Approval Voting (Professor Michael Orrison, Harvey Mudd College)
p-Norm Approval Voting (Professor Michael Orrison, Harvey Mudd College)
Title: p-Norm Approval Voting Speaker: Michael Orrison, Professor of Mathematics, Harvey Mudd College Abstract: Approval voting is a relatively simple voting procedure: Given a set of candidates, each voter chooses a subset of the candidates, and the candidate chosen the most is then declared the winner. Interestingly, approval voting can be viewed as an extreme […]
