We set up an algebraic theory of multivariable integration,based on a hierarchy of Rota-Baxter operators and an action of the matrix monoid as linear substi
In recent years,there have been major developments in applications of integrable systems.Originally,integrability has been recognized through solitons,which
In this talk,we introduce integral-differential algebras.By using the method of Grobner-Shirshov bases,we give the constructions of free commutative integro
