The objective of this paper is to establish certain necessary and sufficient conditions for a multi-scaling function φ := (φ 1 , . . . , φ r ) T to have polynomial reproduction (p. r.) of order m in terms of the eigenvalues and their corresponding eigenvectors of two finite matrices.
The radius of analyticity of periodic analytic functions can be characterized by the decay of their Fourier coefficients. This observation has led to the use of socalled Gevrey norms as a simple way of estimating the time evolution of the spatial radius of analyticity of solutions to parabolic as we
