Stochastic gene expression in switching environments
Martin Gander, Christian Mazza, Hansklaus Rummler
We study a stochastic model proposed recently in the genetic literature to explain the heterogeneity of cell populations or of gene products. Cells are located in two colonies, who…
Long time behavior of the solutions to non-linear Kraichnan equations
Alice Guionnet, Christian Mazza
We consider the solution of a nonlinear Kraichnan equation with a covariance kernel and boundary condition $H…
Simply Generated Trees, B-series and Wigner Processes
Christian Mazza
We consider simply generated trees and study multiplicative functions on rooted plane trees. We show that the associated generating functions satisfy differential equations or diff…
Strand separation in negatively supercoiled dna
Christian Mazza
We consider a model for strand separation in negatively supercoiled dna, and study the effect of supercoiling on the localization of denaturation, using notions from statistical me…
