Auto-correlations of divisor functions in function fields
room MATH 126
Thu 27 Nov 2014, 3:30pm-4:30pm

Abstract

In this seminar I will discuss a function field analogue of a classical problem in analytic number theory, concerning the auto-correlations of divisor functions, in the limit of a large finite field.

Geometric flow on almost Hermitian manifolds towards a symplectic structure
ESB 4133 (PIMS lounge)
Fri 28 Nov 2014, 2:00pm-3:00pm

Abstract

 We propose  geometric flows to study the existence of a symplectic structure on an almost Hermitian manifold. We prove the short-time existence and uniqueness, and show some examples.

Graduate Research Award lecture: Magnetized Target Fusion: Insights from Mathematical Modelling
MATX 1100

Abstract

Magnetized target fusion reactors are a modern design to for hydrogen fusion energy on earth. The design entails confining a plasma with a magnetic field and crushing it in an imploding shell of molten metal. Such a design has many unresolved questions in terms of its feasibility as a power source and the most important elements in making it efficient. In this talk, we will look into two of the approaches undertaken to explore these questions. Firstly, through a coordinate transformation and implementing a novel flux-limited, split-step, finite volume scheme for nonlinear coupled hyperbolic partial differential equations, we do a parameter sensitivity analysis for the design performance. Secondly, by a careful series of asymptotic arguments, we establish a leading order asymptotic expression for the plasma compression. This expression is qualitatively consistent with the numerical work, but it also gives new insights into how the device operates. We will conclude with a look into the viability of magnetized target fusion and its future work.

Note for Attendees

Refreshments will be served at 2:45pm in the Math Lounge area, MATH 125 before the colloquium.

The topological Fukaya category and mirror symmetry for toric Calabi-Yau threefolds
ESB 4127 (host: UBC)
Mon 1 Dec 2014, 3:00pm-4:00pm

Abstract

The Fukaya category of open symplectic manifolds is expected to have good local-to-global properties. Based on this idea several people have developed sheaf-theoretic models for the Fukaya category of punctured Riemann surfaces: the name topological Fukaya category appearing in the title refers to the (equivalent) constructions due to Dyckerhoff-Kapranov, Nadler and Sibilla-Treumann-Zaslow. In this talk I will introduce the topological Fukaya category and explain applications to Homological Mirror Symmetry for toric Calabi-Yau threefolds. This is work in progress joint with James Pascaleff.
