3) solution of differential equations 微分方程的解 1. If this model to be established is composed of autonomy equation(s),it is usually difficult to obtain the solution of differential equations. 此时,可以转移到相平面上,通过分析方程解的稳定性和发展趋势,进而求得微分方程的解。 更多例句>> 4...
A solution with initial conditions given at t = 0 is called singular if it ceases to exist at some finite point T ∈ ( 0 , ∞ ) . Remarkably enough, it is observed that the equation ( ) may admit, in addition to a usual blowing-up singular solution, a completely new type of ...
We study the existence of global solutions of a singular ordinary differential equation arising in the construction of self similar solution for a backward-forward parabolic equation. Also we present several numerical simulations and obt... RENATO COLUCCI - 《Electronic Journal of Differential Equations...

It is shown that for any ball and any k \ge 0, there is a singular solution that satisfies Neumann boundary condition and oscillates at least k times around the constant equilibrium. Moreover, we show that the Morse index of the singular solution is finite or infinite if the exponent is ...

The main purpose of this article is the construction of an electromagnetic field inside the waveguide. We assume the body is located in a semi-infinite rectangular waveguide, and the field propagates in the body. The iteration algorithm based on the solution of the volume integral equation constr...
The solution for Equation (1) represented by Equation (15) is obtained by considering the finite difference method. The analysis of the stability of this solution can be performed analogously to the procedure used to study the stability of the standard equation. The standard diffusion equation is...
