Numerical solving unsteady space-fractional problems with the square root of an elliptic operator

Petr N. Vabishchevich

An unsteady problem is considered for a space-fractional equation in a bounded domain. A first-order evolutionary equation involves the square root of an elliptic operator of secon…
