AbstractA class of Riemann-Hilbert problems arising in Donaldson-Thomas theory has been investigated by Bridgeland. These problems concern mappings from the complex plane to an algebraic torus that exhibit prescribed discontinuities along a set of rays. In this talk, I will begin by reviewing some basics of these Riemann-Hilbert problems, as well as the WKB spectral networks introduced by Gaiot...
AbstractWe propose to revisit the problem of guantisation and look at it from an entirely new analefocusing on the guantisation of dynamical systems themselves, rather than of their Poissonstructures. We begin with a dynamical system defined on a free associative algebra fA generatedby non-commutative dynamical variables al, ac2,..., and reduce the problem of guantisation to theproblem of study...
