Journal of Mathematics, Volume 2026, Issue 1, 2026.This work introduces a nonlinear stochastic Riemann wave equation (SRWE) with particular novel solutions by using the white noise stochastic term. For the considered problem, we have used two computational methods, namely, the auxiliary equation (AE) method and the unified method (UM), for the exact solution and analyzed their various characteristics ...

The generalized tanh-coth method applied to biological model referent to nano-solitons of ionic wave
Applied Mathematical Sciences, 2015 Based on two previous reports related with soliton-solutions for two equations: the rst a biological model and the other a physic model, we consider the generalized tanh-coth method for obtain exact solutions for the rst in a more general form that those obtained in previous reports.

Journal of Mathematics, Volume 2026, Issue 1, 2026.A new negative‐order form of the (3 + 1)‐dimensional Calogero–Bogoyavlenskii–Schiff equation is examined in this investigation. This equation plays an important role in accurately describing the thermodynamic properties of mixtures, particularly in chemical engineering applications.

Journal of Mathematics, Volume 2026, Issue 1, 2026.In this study, the nonlinear partial differential equation that governs the free vibration of a carbon nanotube composite beam is analytically investigated using the truncated M‐fractional derivative. This model is a beam supported by a nonlinear viscoelastic base and reinforced by carbon nanotubes.
