Brownian Motion: Its History And Applications
Fanny Shum (NYU)Wednesday, October 28th, 2020
05:45 PM - 06:35 PM
Storrs Campus Online
Brownian motion is used in many disciplines, such as mathematical physics, probability, and mathematical finance. We will look into the brief history of the development of Brownian motion, also referred to as the Wiener process, and its significance in mathematics. In addition, we will discuss some of its applications.

Smectic liquid crystals are remarkable examples of geometrically frustrated multi-layer system of soft matters. The sutble interplay between the geometry of the layers and equal spacing imposes theoretical complications and understanding the layer structures is a challenging task. In this talk, we shall discuss an approximate nonlinear smectic liquid crystal model in 2 dimensions. Our main results are a compactness theorem for a sequence with bounded energy and a sharp lower bound on the energy. Our analysis indicates that for the 2d model we studied, the defect energy of asymptotically minimal configurations corresponds to the energy of a 1D ansatz, which confirms equipartition between the bending and compression terms in the energy functional is optimal. This is joint work with Michael Novack. -

Join us for the online Logic Colloquium for a talk by Ethan Brauer, Øystein Linnebo, and Stewart Shapiro on:
Divergent potentialism: A modal analysis with an application to choice sequences
Modal logic has recently been used to analyze potential infinity and potentialism more generally. However, this analysis breaks down in cases of divergent possibilities, where the modal logic is weaker than S4.2. This talk has three aims. First, we use the intuitionistic theory of free choice sequences to motivate the need for a modal analysis of divergent potentialism and explain the challenge of connecting the ordinary theory of choice sequences with our modal explication. Then, we use the so-called Beth-Kripke semantics for intuitionistic logic to overcome those challenges. Finally, we apply the resulting modal analysis of divergent potentialism to make choice sequences comprehensible in classical terms.
