Solving nonlinear Klein-Gordon equation with non-smooth solution by a geometric low-regularity integrator
Bin Wang, Zhen Miao, Yaolin Jiang
In this paper, we formulate and analyse a geometric low-regularity integrator for solving the nonlinear Klein-Gordon equation in the -dimensional space with . The integ…
