“Wetterich's equation for regularised QFTs and general probability measures”


címmel tartandó szemináriumára.


Kivonat:



In quantum field theory Wetterich's equation is obtained through a slightly 
modified Legendre transform of Polchinski's equation. It formally satisfies 
an infinite-dimensional partial differential equation with the classical 
action as boundary condition. In a suitable regularisation scheme, the 
equation and its boundary condition can be derived in a mathematically 
rigorous manner. Wetterich's equation can naturally be extended to some class 
of probability measures on locally convex spaces as well. I will discuss the 
ideas and some persisting challenges in this general setting.
