Product Description: In this text, integral geometry deals with Radonâs problem of representing a function on a manifold in terms of its integrals over certain submanifoldsâhence the term the Radon transform. Examples and far-reaching generalizations lead to fundamental problems such as: (i) injectivity, (ii) inversion formulas, (iii) support questions, (iv) applications (e...read more

*About this edition:*Sigurdur Helgason's Differential Geometry and Symmetric Spaces was quickly recognized as a remarkable and important book.Product Description: The theme of this volume is a treatment of differential equations on a $C^\infty$ manifold $V$ by separation of variables techniques. More specifically, given a Lie transformation group $L$ of $V$ and a Lie subgroup $H\subset L$, if $D(V)$ is the set of differential operators on $V$ invariant under $L$, then the principal object of study is the set of distributions $T$ on $V$ satisfying the following two conditions:(i) $T$ is an eigendistribution of each $D\in D(V)$; (ii) $T$ is invariant under $H$...read more
