About the Lectureship:
The аĿª½±Hardy Lectureship is named after G.H. Hardy, former President of the Society and De Morgan Medallist. Originally awarded to a distinguished overseas mathematician in odd-numbered years.
The аĿª½±Hardy Lecturer visits the UK for a period of about two weeks, and gives the Hardy Lecture at a Society meeting, normally held in London in July. The аĿª½±Hardy Lecturer also gives at least six other lectures, on different topics, at other venues in the UK; the schedule is decided by the аĿª½±Society, Lectures and Meetings Committee in consultation with the аĿª½±Hardy Lecturer, and is designed to allow as many UK mathematicians as possible to benefit from the аĿª½±Hardy Lecturer's presence in the UK.
Abstract:
From Symplectic to Poisson manifolds and back
b-Structures and other generalizations (such as E-symplectic structures) are ubiquitous and sometimes hidden, unexpectedly, in a number of problems including the space of pseudo-Riemannian geodesics and regularization transformations of the three-body problem.E-symplectic manifolds include symplectic manifolds with boundary,
manifolds with corners, compactified cotangent bundles and regular symplectic foliations. Their deformation quantization was studied à la Fedosov by Nest and Tsygan. How general can such structures be? In this talk, I first explain how to associate an E-symplectic structure
to a Poisson structure with transverse structure of semisimple type (joint work with Ryszard Nest) and I will connect this to a result by Cahen, Gutt and Rawnsley on tangential star products. This result illustrates how E-symplectic manifolds serve as a trampoline to the
investigation of the geometry of Poisson manifolds and the different facets of their quantization. This should let us address a number of open questions in Poisson Geometry and the study of its quantization from a brand-new perspective.
