We consider the stochastic nonlinear pseudoparabolic equations on the hyperoctant with Dirichlet noise boundary conditions. We establish the local existence and uniqueness of the solution to the initial-boundary value problem with values in an appropriate Sobolev space. We are also interested in the regularity behavior of the solution, especially near the origin, where the boundary data are highly irregular.
Naumkin et al. (Fri,) studied this question.
