Published in 2021 at "Journal of Mathematical Analysis and Applications"

DOI: 10.1016/j.jmaa.2021.125841

Abstract: This paper deals with structural issues concerning wavelet frames and their dual frames. It is known that there exist wavelet frames {aj/2ψ(aj · −kb)}j,k∈Z in L2(R) for which no dual frame has wavelet structure. We… read more here.

Published in 2017 at "Linear Algebra and its Applications"

DOI: 10.1016/j.laa.2017.08.002

Abstract: Abstract We present two methods for constructing new nonseparable multidimensional tight wavelet frames by combining the ideas of sum of squares representations of nonnegative trigonometric polynomials with the coset sum method of generating nonseparable multidimensional… read more here.

Published in 2018 at "Applicable Analysis"

DOI: 10.1080/00036811.2017.1298745

Abstract: ABSTRACT From the literature, it is known that nonhomogeneous dual wavelet frames admit fast wavelet transform as homogeneous ones, and have more designing freedom than homogeneous ones. In this paper, we give a characterization of… read more here.
