Abstract

We introduce the ring of partial differential operators with constant coefficients and commensurate time lags (we use the terminology DΔ\Delta operators from now) initially defined by H. Gl\"using-L\"ur\ss en for ordinary DΔD\Delta operators and investigate its cohomological properties. Combining this ring theoretic observation with the integral representation technique developed by M. Andersson, we solve a certain type of division with bounds. In the last chapter, we prove the injectivity property of various function modules over this ring as well as spectral synthesis type theorems for DΔD\Delta equations.
