Limiting results for the free energy of directed polymers in random environment with unbounded jumps
Francis Comets, Ryoki Fukushima, Shuta Nakajima +1
We study asymptotics of the free energy for the directed polymer in random environment. The polymer is allowed to make unbounded jumps and the environment is given by Bernoulli var…
Localization Transition for Polymers in Poissonian Medium
Francis Comets, Nobuo Yoshida
We study a model of directed polymers in random environment in dimension , given by a Brownian motion in a Poissonian potential. We study the effect of the density and the str…
On exponential growth for a certain class of linear systems
Ryoki Fukushima, Nobuo Yoshida
We consider a class of stochastic growth models on the integer lattice which includes various interesting examples such as the number of open paths in oriented percolation and the…
Stochastic shear thickening fluids: Strong convergence of the Galerkin approximation and the energy equality
Nobuo Yoshida
We consider a stochastic partial differential equation (SPDE) which describes the velocity field of a viscous, incompressible non-Newtonian fluid subject to a random force. Here, t…
Stochastic power law fluids: Existence and uniqueness of weak solutions
Yutaka Terasawa, Nobuo Yoshida
We consider a stochastic partial differential equation (SPDE) which describes the velocity field of a viscous, incompressible non-Newtonian fluid subject to a random force. Here th…
A Note on the Diffusive Scaling Limit for a Class of Linear Systems
Yukio Nagahata, Nobuo Yoshida
We consider a class of continuous-time stochastic growth models on -dimensional lattice with non-negative real numbers as possible values per site. We remark that the diffusive…
