Ring-Theoretic Structures in Generalized Function Algebras: Compact Support, Gaussianity, and Applications Ring-Theoretic Structures in Generalized Function Algebras: Compact Support, Gaussianity, and Applications Author: Shrishti Rastogi | Topics: Colombeau Algebra, Differential Rings, Sheaf Theory Abstract We construct and investigate the ring \(\mathcal{R}\) of compactly supported generalized functions, defined as a subring of the special Colombeau algebra \(\mathcal{G}(\Omega)\). By embedding singularities such as the Dirac delta \(\delta\) and the Heaviside function \(H\) into a differential and topological ring framework, we explore the algebraic and analytic structure of \(\mathcal{R}\). We prove that \(\mathcal{R}\) is a commutative dif...
