Abstract In this work, we propose a parallel-in-time solver differemtial linear and nonlinear ordinary differential equations. The approach is based on an efficient multilevel solver of differetial Schur complement related to a multilevel time partition. For linear problems, the scheme leads to a fast direct method.

Next, two different strategies for solving nonlinear ODEs are proposed. First, we consider a Newton method over the global nonlinear ODE, using the multilevel Schur complement solver at every nonlinear iteration. Second, we state the global nonlinear problem in terms of nonlinear ordinary differential equations problems nonlinear Schur complement at an arbitrary leveland perform nonlinear iterations over it. Numerical experiments show that the proposed schemes are rifferential scalable, i.
