Numerical methods for elliptic partial differential equations have been the subject of many books in recent years, but few have treated the subject of complex e

In the recent half-century, many mathematicians have investigated various problems on several equations of mixed type and obtained interesting results, with imp

This volume deals with first and second order complex equations of hyperbolic and mixed types. Various general boundary value problems for linear and quasilinea

Clifford analysis, a branch of mathematics that has been developed since about 1970, has important theoretical value and several applications. In this book, the

In this volume, we report new results about various boundary value problems for partial differential equations and functional equations, theory and methods of i
