On the Exact Solutions of Two (3+1)-Dimensional Nonlinear Differential Equations

open access: yesJournal of Function Spaces, 2020
In this article, exact solutions of two (3+1)-dimensional nonlinear differential equations are derived by using the complex method. We change the (3+1)-dimensional B-type Kadomtsev-Petviashvili (BKP) equation and generalized shallow water (gSW) equation ...

On a complex differential Riccati equation [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2008
We consider a nonlinear partial differential equation for complex-valued functions which is related to the two-dimensional stationary Schrodinger equation and enjoys many properties similar to those of the ordinary differential Riccati equation as, e.g., the famous Euler theorems, the Picard theorem and others.

Malmquist-type theorems on some complex differential-difference equations

open access: yesOpen Mathematics, 2022
This article is devoted to study the existence conditions of solutions to several complex differential-difference equations. We obtain some Malmquist theorems related to complex differential-difference equations with a more general form than the previous

Structure of complex linear differential equations [PDF]

open access: yesTransactions of the American Mathematical Society, 1982
In this paper homogeneous linear differential equations in the complex domain are considered. Relations between (a) properties of the zeros of solutions, (b) factorization of the equation into linear factors, and (c) nonvanishing of corresponding Wronskians are proved.

Robust discovery of partial differential equations in complex situations

open access: yesPhysical Review Research, 2021
Data-driven discovery of partial differential equations (PDEs) has achieved considerable development in recent years. Several aspects of problems have been resolved by sparse regression-based and neural-network-based methods.

Differential Equations on Complex Manifolds

open access: yes, 2015
We discuss linear partial differential equations with constant coefficients on complex manifold Cn. Using the Sternin-Shatalov integral transform we solve complex Cauchy problem and consider two applications: describe the singularities of the solution of the Cauchy problem and solve a physical problem of sweeping the charge inside the domain (balayage ...
