Partial Differential Equations in Module of Copolynomials of Several Variables over a Commutative Ring

S. L. Gefter, A. L. Piven'

We study the copolynomials of $n$ variables, i.e. $K$-linear mappings from the ring of polynomials $K[x_1,...,x_n]$ into the commutative ring $K$. We prove an existence and uniquen…
