Electronics (Switzerland), 2019 In the current paper, fractional-order hyperbolic telegraph equations are considered for analytical solutions, using the decomposition method based on natural transformation. The fractional derivative is defined by the Caputo operator.

Vacuum block thermalization in semi-classical 2d CFT [PDF]
, 2018 The universal nature of black hole collapse in asymptotically $AdS_3$ gravitational theories suggests that its holographic dual process, thermalization, should similarly be fixed by the universal features of 2d CFT with large central charge $c$.

Sobolev and Max Norm Error Estimates for Gaussian Beam Superpositions [PDF]
, 2015 This work is concerned with the accuracy of Gaussian beam superpositions, which are asymptotically valid high frequency solutions to linear hyperbolic partial differential equations and the Schr\"odinger equation.

Classical torus conformal block, N=2* twisted superpotential and the accessory parameter of Lame equation [PDF]
, 2014 In this work the correspondence between the semiclassical limit of the DOZZ quantum Liouville theory on the torus and the Nekrasov-Shatashvili limit of the N=2* (Omega-deformed) U(2) super-Yang-Mills theory is used to propose new formulae for the ...

Boundary conditions in linearized harmonic gravity [PDF]
, 2001 We investigate the initial-boundary value problem for linearized gravitational theory in harmonic coordinates. Rigorous techniques for hyperbolic systems are applied to establish well-posedness for various reductions of the system into a set of six wave ...

Existence of Weak Solutions for a Hyperbolic Model of Chemosensitive Movement
, 2001 A hyperbolic model for chemotaxis and chemosensitive movement in one space dimension is considered. In contrast to parabolic models for chemotaxis the hyperbolic model allows us to take the dependence of the particle speed on external stimuli explicitly ...

International Journal of Mathematics and Computer in Engineering, 2023 The Pseudo-Hyperbolic Telegraph partial differential equation (PHTPDE) based on the Caputo fractional derivative is investigated in this paper. The modified double Laplace transform method (MDLTM) is constructed for the proposed model. The MDLTM was used

On the Mathematical Character of the Relativistic Transfer Moment Equations [PDF]
, 1994 General--relativistic, frequency--dependent radiative transfer in spherical, differentially--moving media is considered. In particular we investigate the character of the differential operator defined by the first two moment equations in the stationary ...
