Blow-up of solutions for a nonlinear viscoelastic wave equation with initial data at arbitrary energy level
MetadataShow full item record
In this paper, we study a three-dimensional (3D) viscoelastic wave equation with nonlinear weak damping, supercritical sources and prescribed past history (Formula presented.), (Formula presented.): (Formula presented.) where the relaxation function k is monotone decreasing with (Formula presented.), (Formula presented.) and (Formula presented.). When the source is stronger than dissipations, i.e. (Formula presented.), we obtain some finite time blow-up results with positive initial energy. In particular, we obtain the existence of certain solutions which blow up in finite time for initial data at arbitrary energy level.

Optimization over the Pareto outcome set associated with a convex bi-objective optimization problem: theoretical results, deterministic algorithm and application to the stochastic caseBonnel, Henri; Collonge, J. (2014)Our paper consists of two main parts. In the first one, we deal with the deterministic problem of minimizing a real valued function (Formula presented.) over the Pareto outcome set associated with a deterministic convex ...
