Structural Ramsey Theory and Logic (Lynn Scow, CSUSB)

Argue Auditorium, Pomona College 610 N. College Ave., Claremont, CA, United States

Title: Structural Ramsey Theory and Logic Speaker: Lynn Scow, Professor of Mathematics, California State University, San Bernardino Abstract: The connection between Ramsey theory and logic goes back to Frank P. Ramsey's 1929 paper in which he announced his famous Ramsey theorem for finite sequences.  This theorem states that for any partition of all sequences of length […]

İrma Hacınlıyan (Istanbul Technical University)

Emmy Noether Room, Estella 1021, Pomona College, 610 N. College Ave., Claremont, CA, United States

Title: On Nonlinear Schrödinger Type Equations: Wave Modulation and Mathematical Analysis Abstract: The nonlinear Schrödinger (NLS) equation describes the evolution of slowly varying packets of quasi-monochromatic waves in weakly nonlinear dispersive media. The NLS equation with soliton solutions is one of the significant and widely pursued research areas on the nonlinear wave motions. Sub-studies on […]

Claremont Topology Seminar: Joe Breen (University of Iowa)

Estella 2099

We especially welcome all undergraduates and graduate students to attend topology seminar! Speaker: Joe Breen (University of Iowa) Title: Open books in all dimensions Abstract: I will discuss recent work (joint with K. Honda and Y. Huang) on establishing a relationship, first discovered by Giroux, between "contact structures" and "open books". This relationship has been […]

Analysis seminar: Reginald Anderson (CMC)

Estella 2131, Pomona College 610 N College Ave, Claremont, United States

Title: Review of differential geometry Abstract: 1. Given the embedding of a sphere of radius rho centered at the origin of \R^3 from spherical coordinates, what is the pullback of the flat metric in \R^3? i.e., what is the "round metric" on the 2-sphere of radius rho? 2. If we impose a complex structure on S^2 via […]

Emer Lopera Arias (HMC)

Emmy Noether Room, Estella 1021, Pomona College, 610 N. College Ave., Claremont, CA, United States

Title: The fractional p-Laplacian operator. Motivation for its definition and related boundary value problems Abstract: Last decades, nonlocal operators, as the fractional Laplacian, have gained to much attention due to its applications to several physical Phenomena. In this talk we aim to motivate the definition of the fractional laplacian operator through a simple but quite […]

Negligible cohomology (Matthew Gherman, Caltech)

Estella 2099

For a finite group G, a G-module M, and a field F, an element u in H^d(G,M) is negligible over F if for each field extension L/F and every continuous group homomorphism from Gal(L^{sep}/L) to G, u is in the kernel of the induced homomorphism H^d(G,M) to H^d(L,M). Negligible cohomology was first introduced by Serre […]

Claremont Topology Seminar: Elena Wang (Michigan State University)

Estella 2099

We welcome all undergraduates and graduate students to attend topology seminar! Speaker: Elena Wang (Michigan State University) Title: A Distance for Geometric Graphs via the Labeled Merge Tree Interleaving Distance Abstract: Geometric graphs appear in many real-world data sets, such as road networks, sensor networks, and molecules. We investigate the notion of distance between graphs […]

CCMS Colloquium: Inaugurual Barbara Beechler Lecture

CCMS Colloquium invites you to the final talk of the 2023-2024 academic year and the inaugural Barbara Beechler Lecture by Professor Judy Grabiner, Flora Sanborn Pitzer Professor of Mathematics Emerita. Title: It’s All for the Best: Optimization in the History of Science Abstract: Many problems, from optics to economics, can be solved mathematically by finding […]

Lattice angles and quadratic forms (Lenny Fukshansky, CMC)

Estella 2099

What are the possible angles between two integer vectors in R^n? If we fix one such possible angle and one integer vector x, is there always another integer vector y that makes this angle with x? Assuming that x makes a given angle with some vector, how can we find the shortest such vector y? […]

Applied Math Seminar: Christina Edholm (Scripps College)

Estella 1021 (Emmy Noether Room), Pomona College Claremont, CA, United States

Title: Controlling the unmanageable: insight into control methods for biological systems Abstract: When formulating a model for a biological system, often we want to use the model to understand the implications of management options and how to optimize the implementation. There are various methods for implementing management through control theory, ranging from basic, optimal control, […]
