The strong Feller property for singular stochastic PDEs
M Hairer, J Mattingly - 2018 - projecteuclid.org
We show that the Markov semigroups generated by a large class of singular stochastic
PDEs satisfy the strong Feller property. These include for example the KPZ equation and the …

Stochastic quantization associated with the -quantum field model driven by space-time white noise on the torus
M Hoshino, H Kawabi, S Kusuoka - Journal of Evolution Equations, 2021 - Springer
We consider a quantum field model with exponential interactions on the two-dimensional
torus, which is called the\exp (Φ) _ 2 exp (Φ) 2-quantum field model or Høegh-Krohn's …
