On the support of solutions to the heat equation with noise

- C. Mueller
- Mathematics
- 1 December 1991

Let be 2-parameter white noise. Let satisfy and suppose that is bounded, nonnegative, with compact support and not identically 0. We show that with probability for all . This complements results of… Expand

Some Non-Linear S.P.D.E's That Are Second Order In Time

- Robert C. Dalang, C. Mueller
- Mathematics
- 1 July 2002

We extend J.B. Walsh's theory of martingale measures in order to deal with stochastic partial differential equations that are second order in time, such as the wave equation and the beam equation,… Expand

The Length of the Longest Increasing Subsequence of a Random Mallows Permutation

- C. Mueller, S. Starr
- Mathematics, Physics
- 16 February 2011

The Mallows measure on the symmetric group Sn is the probability measure such that each permutation has probability proportional to q raised to the power of the number of inversions, where q is a… Expand

Regularity of the density for the stochastic heat equation

- C. Mueller, D. Nualart
- Mathematics
- 17 September 2007

We study the smoothness of the density of a semilinear heat equation with multiplicative spacetime white noise. Using Malliavin calculus, we reduce the problem to a question of negative moments of… Expand

Interacting particles, the stochastic Fisher–Kolmogorov–Petrovsky–Piscounov equation, and duality

- C. Doering, C. Mueller, P. Smereka
- Mathematics, Physics
- 1 July 2003

The stochastic Fisher–Kolmogorov–Petrovsky–Piscunov equation is∂tU(x,t)=D∂xxU+γU(1−U)+eU(1−U)η(x,t)for 0⩽U⩽1 where η(x,t) is a Gaussian white noise process in space and time. Here D, γ and e are… Expand

Long time existence for the wave equation with a noise term

- C. Mueller
- Mathematics
- 1997

We consider the equationut=uxx+uγ W forx on a finite interval, with Dirichlet boundary conditions. W is spacetime white noise. The initial condition is continuous and nonnegative. We show existence… Expand

SummaryWe consider all solutions of a martingale problem associated with the stochastic pde
$$u_t = \tfrac{1}{2}u_{xx} + u^\gamma \dot W$$
and show thatu(t,·) has compact support for allt≧0 ifu(0,·)… Expand
