I review the Feynman-Wiener path-integral formalism for diffusion with drift and jumps.
The past decade has seen a revived interest in the unavoidable or intrinsic noise in biochemical and genetic networks arising from the finite copy number of the participating species. That is, rather than modeling regulatory networks in…
