Gravitational path integral from the T 2 deformation

Journal of High Energy Physics, 2020
We study a T 2 deformation of large N conformal field theories, a higher dimensional generalization of the T T ¯ $$ T\overline{T} $$ deformation. The deformed partition function satisfies a flow equation of the diffusion type.

Some novel integration techniques to explore the conformable M-fractional Schrödinger-Hirota equation

Journal of Ocean Engineering and Science, 2022
The current study deals with exact soliton solutions for Schrödinger-Hirota (SH) equation via two modified integration methods. Those methods are known as the improved (G′/G)-expansion method and the Kudryashov method. This model is a generalized version

Hexagonal vs. Rectilinear Grids for Explicit Finite Difference Schemes for the Two-dimensional Wave Equation [PDF]

, 2013
Finite difference schemes for the 2-D wave equation operating on hexagonal grids and the accompanyingnumerical dispersion properties have received little attention in comparison to schemes operating on rectilinear grids.

Two-way coupling model for wave-induced oscillatory soil response around marine structures [PDF]

, 2022
Considerable efforts have been devoted to the topic of wave–seabed interactions in the last two decades because of growing offshore activities. The existing studies have based on one-way coupling approach.

A (3 + 1)-dimensional nonlinear extended Zakharov–Kuznetsov dynamical equation: Bifurcation and traveling wave solutions

AIP Advances, 2020
This paper studies the (3 + 1) extended Zakharov–Kuznetsov (EZK) dynamical equation that is utilized to describe nonlinear three-dimensional dust-ion-acoustic solitary waves in a magnetized two-ion-temperature dusty plasma.

A Modified Equation Approach to Selecting a Nonstandard Finite Difference Scheme Applied to the Regularized Long Wave Equation

Abstract and Applied Analysis, 2014
Two nonstandard finite difference schemes are derived to solve the regularized long wave equation. The criteria for choosing the “best” nonstandard approximation to the nonlinear term in the regularized long wave equation come from considering the ...

Preliminary Investigation of Wavefield Depth Extrapolation by Two-Way Wave Equations

International Journal of Geophysics, 2012
Most of the wavefield downward continuation migration approaches are relying on one-way wave equations, which move the seismic energy always in one direction along depth. The one-way downward continuation migrations only use the primaries for imaging and do not treat secondary reflections recorded on the surface correctly. In this paper, we investigate
