Abstract
We introduce a new imaginary-Brownian-time-Brownian-angle process, which we also call the linear-Kuramoto-Sivashinsky process (LKSP). Building on our techniques in two recent articles involving the connection of Brownian-time processes to fourth order PDEs, we give an explicit solution to a linearized Kuramoto-Sivashinsky PDE in -dimensional space: $\scriptstyle{\eight{u_t=-\frac18Δ^2u-\frac12Δu-\frac12u}}$. The solution is given in terms of a functional of our LKSP.
