Positive expression for non-negative polynomal matrices on strips of the form U×R in R^2 where U⊆R is compact

Abstract

Based on the positive expression for non-negative polynomals on strips of the form  in , where  is compact, at article [1], we present and prove the positive expression for non-negative polynomal matrices or polynomals with coefficients of matrices. In concrete, we show diagonal polynomal matrices and then polynomial symmetric matrices.
