Parametric Factorizations of Second-, Third- and Fourth-Order Linear Partial Differential Operators with a Completely Factorable Symbol on the Plane
Ekaterina Shemyakova
Parametric factorizations of linear partial operators on the plane are considered for operators of orders two, three and four. The operators are assumed to have a completely factor…

Obstacles to the Factorization of Linear Partial Differential Operators into Several Factors
Ekaterina Shemyakova, Franz Winkler
We consider algorithms for the factorization of linear partial differential operators. We introduce several new theoretical notions in order to simplify such considerations. We def…
