The Gelfand–Shilov Type Estimate for Green’s Function of the Bounded Solutions Problem

“…In this Section we prove an estimate of Green's function. As a potential application of this estimate, we note that knowing an estimate of the function t → G(t) is an important information in the freezing method for equations with slowly varying coefficients [ [1,3,18,19,25,27,28]. See also references therein.…”
