On the relaxation of special demi-coercive functionals in the space SBD(Ω)
Integral representation relaxation,special
2011/10/18
In this paper,we obtain an integral representation for the relaxation of the special demi-coercive functional \\[ F(x,u,\\Omega):=\\left\\{ \\begin{array}{ll} \\int_{\\Omega}f(x,u(x),\\varepsilon u(x)...
Time relaxation of a phase-field model with entropy balance
phase-field model entropy balance Analysis of PDEs
2011/9/14
Abstract: We deal with a system of two coupled differential equations, describing the evolution of a first order phase transition. In particular, we have two non-linear parabolic equations: the first ...
Approximation and relaxation of perimeter in the Wiener space
Approximation and relaxation of perimeter the Wiener space Analysis of PDEs
2011/9/13
Abstract: We characterize the relaxation of the perimeter in an infinite dimensional Wiener space, with respect to the weak L^2-topology. We also show that the rescaled Allen-Cahn functionals approxim...
Implicit-explicit Runge-Kutta schemes and applications to hyperbolic systems with relaxation
Runge-Kutta methods hyperbolic systems with relaxation stiff systems
2010/12/6
We consider new implicit-explicit (IMEX) Runge-Kutta methods for hyperbolic systems of conservation laws with stiff relaxation terms. The explicit part is treated by a strong-stability-preserving (SSP...
In this paper we consider continuous-time and discrete-time waveform relaxation methods for general nonlinear integral-differential-algebraic equations. For the continuous-time case we derive the conv...
