Theory and internal structure of ADER-DG method for partial differential equations
I. S. Popov
Highly accurate stability boundary values for the ADER-DG method are obtained for arbitrary degrees of basis polynomials. In the linear case, stability is violated precisely wh…

Improving the local solution of the DG predictor of the ADER-DG method for solving systems of ordinary differential equations and its applicability to systems of differential-algebraic equations
I. S. Popov
Improved local numerical solution for the ADER-DG numerical method with a local DG predictor for solving the initial value problem for a first-order ODE system is proposed. The imp…
