American Journal of Mathematics, Vol. 120, No. 6 (Dec., 1998), pp. 1277-1287 (11 pages) A theorem of Cassidy states that any Zariski closed differential algebraic subgroup of a simple linear algebraic ...

Let G be a reductive linear algebraic group over an algebraically closed field of characteristic p > 0. A subgroup of G is said to be separable in G if its global and infinitesimal centralizers have ...

Differential Galois theory extends the classical study of algebraic symmetries into the realm of differential equations. This area investigates the relationship between a differential equation’s ...

Algebraic groups and their representations lie at the heart of modern mathematics, forming a bridge between abstract algebraic structures and geometric intuition. The study of algebraic groups entails ...
