Claremont Topology Seminar: Scott Taylor (Colby College)

Estella 2099, Pomona College 610 N. College Ave., Claremont, CA, United States

We especially welcome all undergraduates and graduate students to attend topology seminar! Speaker: Scott Taylor (Colby College) Title: Genus 1 Bridge Number of Satellite Knots in Lens Spaces Abstract: In the mid-1950s, Horst Schubert introduced two ideas which turned out to have lasting impact in knot theory: satellite knots and bridge number. A Satellite knot […]

Claremont Topology Seminar: Reginald Anderson (Claremont McKenna College)

Estella 2099, Pomona College 610 N. College Ave., Claremont, CA, United States

We especially welcome all undergraduates and graduate students to attend topology seminar! Speaker: Reginald Anderson (Claremont McKenna College) Title: Kontsevich's Recursive Formula for Rational Plane Curves Abstract: Gromov-Witten theory was developed in the 1990s as a curve-counting theory by integrating cohomology classes against a virtual fundamental class for a moduli space of stable maps. One […]

Claremont Topology Seminar: Iris Yoon (Wesleyan University)

Estella 2099, Pomona College 610 N. College Ave., Claremont, CA, United States

We especially welcome all undergraduates and graduate students to attend topology seminar! Speaker: Iris Yoon (Wesleyan University) Title: Dowker duality, profunctors, and spectral sequences Abstract: I will present three short, new proofs of Dowker duality using various poset fiber lemmas. I will introduce modifications of joins and products of simplicial complexes called relational join and […]

Claremont Topology Seminar: Carrie Frizzell (Scripps College)

Estella 2099, Pomona College 610 N. College Ave., Claremont, CA, United States

We especially welcome all undergraduates and graduate students to attend topology seminar! Speaker: Carrie Frizzell (Scripps College) Title: A Primer on Tropical Geometry Abstract: Max-plus and min-plus semifields—coined tropical semifields—appeared in the 1970s in the work of the computer scientist Imre Simon. Since then, the field of tropical geometry has developed rapidly. In this talk, […]

Claremont Topology Seminar: Morgan Weiler (University of California, Riverside)

Estella 2099, Pomona College 610 N. College Ave., Claremont, CA, United States

We especially welcome all undergraduates and graduate students to attend topology seminar! Speaker: Morgan Weiler (University of California, Riverside) Title: Anchored symplectic embeddings and 2-parameter persistence Abstract: Symplectic geometry is a generalization of classical mechanics, in which position and momentum coordinates are paired. In two dimensions, symplectic geometry is equivalent to volume-preserving geometry, but in […]

Claremont Topology Seminar: Shane Rankin (University of California, Riverside)

Estella 2099, Pomona College 610 N. College Ave., Claremont, CA, United States

We especially welcome all undergraduates and graduate students to attend topology seminar! Speaker: Shane Rankin (University of California, Riverside) Title: Symplectic Hodge Theory on Lie Algebroids Abstract: Symplectic Hodge Theory was developed in the late 80s to answer a conjecture of Brylinksi. Since then it has been used to understand the gap between Symplectic and […]

Claremont Topology Seminar: Heather Lee

Estella 2099, Pomona College 610 N. College Ave., Claremont, CA, United States

We welcome all undergraduate/graduate students and faculty to attend topology seminar! Speaker: Heather Lee Title: Some examples of homological mirror symmetry Abstract: Mirror symmetry is a duality phenomenon between symplectic geometry and complex geometry. The homological mirror symmetry (HMS) conjecture was originally formulated by M. Kontsevich in 1994 to fully capture this phenomenon for mirror […]

Claremont Topology Seminar: Will Hoffer (UC Riverside)

Estella 2099, Pomona College 610 N. College Ave., Claremont, CA, United States

We welcome all undergraduate/graduate students and faculty to attend topology seminar! Speaker: Will Hoffer (UC Riverside) Title: Tube Formulae for Fractal Snowflakes Abstract: Fractals like the von Koch snowflake have rough boundaries, often having nowhere defined tangent lines/spaces. However, there is a tool useful for probing the edges of such fractals: tubular neighborhoods. In this […]
