Background Combination therapy with an immunomodulator (IMM) and an anti-TNF agent (specifically infliximab) is recommended in Crohn’s disease (CD) and ulcerative colitis (UC) patients to improve efficacy and reduce anti-TNF immunogenicity. Combo t

We study some of the main features of Fractional Step Runge–Kutta–Nyström methods when they are used to integrate Initial–Boundary Value Problems of second order in time, in combination with a suitable spatial discretization. We focus our atte

In this paper, a general procedure is given to construct explicit high-order symmetric multistep cosine methods. For these integrators, stability for stiff problems and order of consistency under hypotheses of regularity are justified. We also study

In a previous paper, some particular multistep cosine methods were constructed which proved to be very efficient because of being able to integrate i n a stable and explicit way linearly stiff problems of second-order in time. In the present paper, t

We present a new class of efficient time integrators for solving linear evolution multidimensional problems of second-order in time named Fractional Step Runge-Kutta-Nystrom methods (FSRKN). We show that these methods, combined with suitable spliting

In this paper, it is proved the stability of rational methods for the time discretization of abstract well-posed second order in time problems where the differential operator generates a cosine function. The particular case of operators associated to

In this paper we construct and analyse some multistep methods that integrate exactly the stiff part of a second-order partial differential equation. Much emphasis is given to symmetric methods of this type in order to deal with Hamiltonian problems.

We study the order of consistency and convergence which arises when implicit Runge-Kutta-Nystrom methods are used for the time discretization of linear second-order in time partial differential equations. The order reduction observed in practice, inc

The definition of stability for Runge–Kutta–Nystrom methods applied to stiff second-order in time problems has been recently revised, proving that it is necessary to add a new condition on the coefficients in order to guarantee the stability. In

In this paper, a general and detailed study of linear stability of Runge–Kutta–Nyström (RKN) methods is given. In the case that arbitrarily stiff problems are integrated, we establish a condition that RKN methods must satisfy so that a uniform b
