Blow-up phenomena for a pseudo-parabolic system with variable exponents

摘要

In this paper, we consider a pseudo-parabolic system with nonlinearities ofvariable exponent type associated with initial and Dirichlet boundary conditions, where the variable exponentsp(·), m(·), n(·) are continuous functions on W. We obtain an upper bound and a lowerbound for blow-up time if variable exponents p(·), m(·), n(·) and the initial data satisfysome conditions.
