Stability of numerical solution to pantograph stochastic functional differential equations

作者:

Highlights:

• We study a new type of stochastic functional differential equation. The PSFDEs differs markedly from PSDEs, since the current state of PSFDEs depends on a past segment of its solution while the current state of PSDEs depends only on a past point of its solution.

• We are the first to give the definition of the approximate solution for PSFDEs. The approximate solution converges strongly to the analytical solution in finite time interval.

• The numerical solutions preserve the exponential stability and polynomial stability of the analytical solution under the certain conditions.
