Krall-Jacobi commutative algebras partial differential operators
2010/11/18
We construct a large family of commutative algebras of partial differential operators invariant under rotations. These algebras are isomorphic extensions of the algebras of ordinary differential oper...

Factoring Zero-dimensional Ideals Linear Partial Differential Operators
2013/9/3
We present an algorithm for factoring a zero-dimensional left ideal in the ring Q(x; y)[@x; @y ], i.e. factoring a linear homogeneous partial di erential system whose coecients belong to Q(x; y), and...
