Properties of the energy Laplacian on Sierpinski gasket type fractals
In this paper,we extend some results from the standard Laplacian on the Sierpinski Gasket to the energy Laplacian. We evaluate the pointwise formula for the energy Laplacian and then observe that we have the analogue of Picard’s existence and uniqueness ...

Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT This paper develops a mathematical framework for interpreting observations of solar inertial waves in an idealized setting. Under the assumption of purely toroidal linear waves on the sphere, the stream function of the flow satisfies a fourth‐order scalar equation.

On Normalized Signless Laplacian Resolvent Energy
Kragujevac Journal of MathematicsSummary: Let \(G\) be a simple connected graph with \(n\) vertices. Denote by \(\mathcal{L}^+(G) =D(G)^{-1/2}Q(G) D(G)^{-1/2}\) the normalized signless Laplacian matrix of graph \(G\), where \(Q(G)\) and \(D(G)\) are the signless Laplacian and diagonal degree matrices of \(G\), respectively. The eigenvalues of matrix \(\mathcal{L}^+(G)\), \(2=\gamma_1^+

New Bounds on the Normalized Laplacian (Randic) Energy
, 2018 In this paper, we consider the energy of a simple graph with respect to its normalized Laplacian eigenvalues (Randic eigenvalues), which we call the normalized Laplacian energy (also Randic energy).

Proteins: Structure, Function, and Bioinformatics, EarlyView.ABSTRACT The GTPase KRAS executes a conformational switch between a GTP‐bound active state and a GDP‐bound inactive state, a process central to oncogenic signaling. However, the structural basis of this switching at the level of residue‐contact organization remains incompletely characterized by traditional binary structural models.
