In this paper, we introduce a new approach to solving fractional initial and boundary value problems involving heat equation, wave telegraph equation by modifying the double Sumudu transform of type. We discuss modified conformable together with conditions for its existence. addition, prove some more properties fractional-type transform, including convolution other properties, which are well kn...

We introduce a generalized Crofoot transform between the model spaces corresponding to matrix-valued inner functions. As an application, we obtain results about truncated Toeplitz operators.

Wavelet transformation is one of the most practical mathematical transformations in the field of image processing, especially image and signal processing. Depending on the nature of the multiresolution analysis, Wavelet transformation become more accessible and powerful tools. In this paper, we refer to the mathematical foundations of this transformation.   Introduction: The...
