Elliptic General Analytic Solutions [PDF]

open access: yesStudies in Applied Mathematics, 2009
To find analytically the traveling waves of partially integrable autonomous nonlinear partial differential equations, many methods have been proposed over the ages: “projective Riccati method,”“tanh‐method,”“exponential method,”“Jacobi expansion method,”“new … ,” etc.

Analytic solution of Bremsstrahlung TBA [PDF]

open access: yesJournal of High Energy Physics, 2012
We consider the quark--anti-quark potential on the three sphere or the generalized cusp anomalous dimension in planar N=4 SYM. We concentrate on the vacuum potential in the near BPS limit with $L$ units of R-charge. Equivalently, we study the anomalous dimension of a super-Wilson loop with L local fields inserted at a cusp. The system is described by a

Analytical solution of non-linear fractional diffusion equation

open access: yesAdvances in Difference Equations, 2021
In this paper, we obtain an approximate/analytical solution of nonlinear fractional diffusion equation using the q-homotopy analysis transform method. The existence and uniqueness of the solution for this problem are also derived.
