# Math Physics Seminar

Speaker:
Shaikh Gohin Samad (University of Toledo)
Topic:
Stochastic PDE and Quantum Fields

Abstract:

In scalar case, the existence of quantum field is equivalent to the existence of a Euclidean-invariant reflection positive measure on the Schwartz space tempered distributions. Stochastic quantization is realized as a method of obtaining the measure dμ(ϕ) on Schwartz distribution space as the limit λ ⤑ ∞ of sequence of measures  dμλ(ϕ) defined by a dynamical equation for a field subjected to a random force. Martin Hairer investigated random fields by studying non-linear stochastic partial differential equation with a white noise'' driving term. In this talk we will investigate the question whether a quantum field can be obtained from the measure on the solution induced by the stochastic driving term.
