In this paper, we introduce matrix-valued multiresolution analysis and orthogonal matrix-valued wavelets. We obtain a necessary and sufficient condition on the
In this paper, we consider the inverse scattering by chiral obstacle in electromagnetic fields, and prove that the linear sampling method is also effective to d
Let ω be the element of maximal length in a finite irreducible Coxeter system (W, S). In the present paper, we get the length of ω when (W, S) is of type An,
