Modified Atangana-Baleanu fractional operators involving generalized Mittag-Leffler function
Alexandria Engineering Journal, 2023 In this paper, we are going to deal with fractional operators (FOs) with non-singular kernels which is not an easy task because of its restriction at the origin.

Laplace invariants of differential operators [PDF]
Illinois Journal of Mathematics, 2021 We identify conditions giving large natural classes of partial differential operators for which it is possible to construct a complete set of Laplace invariants. In order to do that we investigate general properties of differential invariants of partial differential operators under gauge transformations and introduce a sufficient condition for a set of

Diagram Technique for the Heat Kernel of the Covariant Laplace Operator [PDF]
Theoretical and mathematical physics, 2019 We present a diagram technique used to calculate the Seeley–DeWitt coefficients for a covariant Laplace operator. We use the combinatorial properties of the coefficients to construct a matrix formalism and derive a formula for an arbitrary coefficient.

Cheeger‐like inequalities for the largest eigenvalue of the graph Laplace operator [PDF]
Journal of Graph Theory, 2019 We define a new Cheeger‐like constant for graphs and we use it for proving Cheeger‐like inequalities that bound the largest eigenvalue of the normalized Laplace operator.

Laplace and Dirac operators on graphs
Linear and Multilinear Algebra, 2022 Discrete versions of the Laplace and Dirac operators haven been studied in the context of combinatorial models of statistical mechanics and quantum field theory. In this paper we introduce several variations of the Laplace and Dirac operators on graphs, and we investigate graph-theoretic versions of the Schr dinger and Dirac equation.

Medical Image Enhancement Based on Laplace Transform, Sobel Operator and Histogram Equalization
Academic Journal of Computing & Information Science, 2022 : Medical image enhancement is one of the most widely used medical image processing techniques in medical domain. Its purpose is to improve the visual effect of the image and facilitate the analysis and understanding of the image by human or machine. The
