Numerical Solution of?Non-stationary Problems with?a?Rational Approximation for?Fractional Powers of includes the fractional power of a self-adjoint positive operator. In computational practice, rational approximations of the fractional power operator are widely used. In this work, we construct special time approximations with fractional power operators: the transition to a new level in time provi

An Exact Schur Complement Method for?Time-Harmonic Optimal Control Problems equation decouples for the different frequencies. Hence, for the analysis of a solution method one can consider the frequency as a parameter. There are three variables to be determined, the state solution, the control variable, and the adjoint variable..The first order optimality conditions lead to

On the?Consistency Order of?Runge–Kutta Methods Combined with?Active Richardson Extrapolationnvergence is shown to increase by one under rather natural smoothness conditions if the passive Richardson extrapolation is used, for the active Richardson extrapolation the increase of the order has not been generally proven. It is known that the Lipschitz property of the right-hand side function o

Quantum Effects on?1/2[111] Edge Dislocation Motion in?Hydrogen-Charged Fe from?Ring-Polymer Moleculing of HE requires a more detailed description of dislocation motion in combination with the diffusion and trapping of H atoms. A serious obstacle towards the atomistic modelling of a H interstitial in Fis associated with the role nuclear quantum effects (NQEs) might play evenat room temperatures, d

Degeneracy of?Tetrahedral Partitions Produced by?Randomly Generated Red Refinementsique subdivides each tetrahedron into 8 subtetrahedra with equal volumes. However, in contrast to triangular partitions, the red refinement strategy is not uniquely determined for the case of tetrahedral partitions which leads to the fact that randomly performed red refinements may produce degenerat
