My research subject is analysis of partial differential equations of hyperbolic type with irregular singularities. Such equations have asymptotic solutions, which do not converge, in general. However, we construct microlocal solutions for weakly hyperbolic equations. The singularities of the solutions are in one of the characteristic roots of the hyperbolic operators. I study a relationship between these microlocal solutions and integral representation of solutions. Computational analysis for differential equations is also my subject. |
