On a Class of Elliptic Operators with Unbounded Time- and Space-dependent Coefficients in ℝN

  • Chapter
Functional Analysis and Evolution Equations

Abstract

We prove optimal Schauder estimates for classical solutions of the nonhomogeneous Cauchy problem associated with a class of elliptic operators with unbounded coefficients depending both on time and space variables. We deal both with the case when the coefficients of the elliptic operator are continuous and the case when they are merely measurable in the pair (t, x). In both the cases we assume that they are Hölder continuous in x, uniformly with respect to t.
