In the present work, the tamed Euler method is proven to be strongly
convergent for stochastic differential equations with piecewise continuous
arguments and Poisson jumps, where the diffusion and jump coefficients are
globally Lipschitz continuous, the drift coefficient is one-sided Lipschitz
continuous, and its derivative demonstrates an at most polynomial growth.
Moreover, the convergence rate is obtained.
