Orthogonal Systems of Spline Wavelets as Unconditional Bases in Sobolev Spaces
Rajula Srivastava
We exhibit the necessary range for which functions in the Sobolev spaces can be represented as an unconditional sum of orthonormal spline wavelet systems, such as the Battl…

A Cotlar Type Maximal Function Associated With Fourier Multipliers
Rajula Srivastava
We prove the boundedness of a maximal operator associated with a dyadic frequency decomposition of a Fourier multiplier, under a weak regularity assumption.
