The study of differential operators within the framework of Lie groups offers a profound gateway into understanding symmetry, geometry and representation theory. At its core, this area investigates ...

The importance of similarity transformations and their applications to partial differential equations is discussed. The theory has been presented in a simple manner so that it would be beneficial at ...

MR MURRAY'S book is adapted to provide for students that knowledge of the subject of differential equations which they are likely to want in applications of mathematics to physics, and in the general ...

Suppose $G$ is a noncompact, connected, semisimple Lie group with finite center and $K$ is a maximal compact subgroup. Let $D$ be an $\operatorname{Ad} K$-invariant ...
