  • CCMS Colloquium: Konstantin Zuev (Caltech)

    Davidson Lecture Hall, CMC 340 E 9th St, Claremont, CA, United States

    CCMS Colloquium invites you to a talk by Konstantin Zuev (Caltech) Title: Course-Prerequisite Networks Abstract: An academic curriculum is a complex system of courses and their interactions that lies at […]

  • GEMS December 6th Session

    Shanahan B450, Harvey Mudd College 301 Platt Blvd., Claremont, United States

    This GEMS session will be facilitated by Professor Ryan Aschoff from the Claremont Graduate University. Title: Randomness: Creating Order from Chaos Abstract: From the hiss of white noise to the gentle hum of ocean waves, randomness surrounds us — yet hidden within that chaos lies remarkable order. In this talk, we’ll explore how unpredictable events, […]

  • Fractional Brownian Motion: Small Increments and First Exit Time from One-sided Barrier (Qidi Peng, CGU)

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

    Abstract: The talk introduces a conjecture on the first exit time of fractional Brownian motion: the upper-tail probability for a fractional Brownian motion to first exit a positive-valued barrier over time T has the exact asymptotic rate T^(H-1), where H is the Hurst parameter of the fractional Brownian motion. The talk tries to understand this conjecture […]

  • The forbidden quiver of a link (Sam Nelson, CMC)

    Estella 2099

    Virtual links can be represented as equivalence classes of Gauss diagrams under Reidemeister moves. The Forbidden Moves are moves which look plausible but change the virtual isotopy class of the knot or link -- indeed, virtual knots are all trivial if we allow forbidden moves. However, virtual links remain non-trivial. In this talk we show […]

  • Sampling from the proper colorings of a graph using a number of colors linear in the maximum degree in expected linear time (Mark Huber, CMC)

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

    Abstract: A proper coloring of a graph is an assignment of colors from \( \{1, 2, \ldots, k\} \) to each node of a graph such that no two nodes connected by an edge receive the same color. Let \( \Delta \) denote the maximum degree of the graph. If \( k \geq \Delta + […]

  • CCMS Colloquium: John Baez (UCR)

    Davidson Lecture Hall, CMC 340 E 9th St, Claremont, CA, United States

    CCMS Colloquium invites you to a talk by John Baez (UCR) Title: The mathematics of tuning systems Abstract: Leibniz said "Music is the pleasure the human mind experiences from counting without being aware that it is counting."  The first step is choosing a tuning system — the frequency ratios between pitches in a scale.  Different kinds […]

  • Relationships between skein algebras (Helen Wong, CMC)

    Estella 2099

    We will examine the multiplicative structure of two skein algebras--- the usual Kauffman bracket skein algebra of a surface (generated by loops) and a generalization of it due to Roger-Yang (generated by loops and arcs).   In joint work with Chloe Marple, we found a homomorphism between the usual skein algebra for a closed torus and […]

  • CCMS Colloquium: Teal Witter (CMC)

    Davidson Lecture Hall, CMC 340 E 9th St, Claremont, CA, United States

    CCMS Colloquium invites you to a talk by Teal Witter (CMC) Title: Exactly Computing do-Shapley Values Abstract:  Causal questions lie at the heart of scientific inquiry, from evaluating economic policies to determining medical treatments. Yet, observational data alone is often insufficient due to the fundamental problem of causal inference: we cannot observe the counterfactual world […]

  • GEMS February 7th Session

    Shanahan B450, Harvey Mudd College 301 Platt Blvd., Claremont, United States

    This GEMS session will be facilitated by Professor Teal Witter from Claremont McKenna College. Title: Who Can Write Down the Bigger Number? Abstract: If you had fifteen seconds to write the largest distinct whole number possible on an index card, what would you write? While most would look to the physical world for inspiration—counting the […]

  • A BKM-type criterion for the 3D incompressible Euler equations (Mustafa Aydin, USC)

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

    Abstract: The three-dimensional incompressible Euler equations describe the motion of an ideal fluid, yet the mechanisms that govern the possible loss of regularity of smooth solutions remain only partially understood. A classical result of Beale, Kato, and Majda shows that if a smooth solution breaks down in finite time, then the time integral of the […]

    Davidson Lecture Hall, CMC 340 E 9th St, Claremont, CA, United States
