Abstract
We review our algebraic framework for linear boundary problems (concentrating on ordinary differential equations). Its starting point is an appropriate algebraization of the domain of functions, which we have named integrodifferential algebras. The algebraic treatment of boundary problems brings up two new algebraic structures whose symbolic representation and computational realization is based on canonical forms in certain commutative and noncommutative polynomial domains. The first of these, the ring of integrodifferential operators, is used for both stating and solving linear boundary problems. The other structure, called integrodifferential polynomials, is the key tool for describing extensions of integrodifferential algebras. We use the canonical simplifier for integrodifferential polynomials for generating an automated proof establishing a canonical simplifier for integrodifferential operators. Our approach is fully implemented in the THEOREMA system; some code fragments and sample computations are included.
