In this paper we study the action of A on f ( the spline of order n with nodes az+) and on its wavelet coefficients, where A = is a double infinite matrix operator in a Hilbert space l 2(z+). Also, we make an attempt to find frame conditions for A-transform of f.

Let R be a ring and I an ideal of R. We define and study I-pure submodules , I-FP-injective modules, I-flat modules , I-coherent rings and I-semihereditary rings. Using the concepts of I-FP-injectivity and I-flatness of modules, we also present some characterizations of I-coheren...
