Analysis of an abstract mixed formulation for viscoelastic problems
Erwin Hernández, Felipe Lepe, Jesus Vellojin
This study provides an abstract framework to analyze mixed formulations in viscoelasticity, in the classic saddle point form. Standard hypothesis for mixed methods are adapted to t…
A mixed parameter formulation with applications to linear viscoelasticity
Erwin Hernández, Felipe Lepe, Jesus Vellojin
In this work we propose and analyze an abstract parameter dependent model written as a mixed variational formulation based on Volterra integrals of second kind. For the analysis, w…
A locking-free optimal control problem with cost for optimal placement of control devices in Timoshenko beam
Erwin Hernández, Pedro Merino
The numerical approximation of an optimal control problem with -control of a Timoshenko beam is considered and analyzed by using the finite element method. From the practical…
Exceptional points and unitary evolution of the physical solutions
E. Hernández, A. Jáuregui, D. Lohr +1
An example of exceptional points in the continuous spectrum of a real, pseudo-Hermitian Hamiltonian of von Neumann-Wigner type is presented and discussed. Remarkably, these excepti…
Dissipative dynamics of vortex lines in superfluid He
H. M. Cataldo, M. A. Despósito, E. S. Hernández +1
We propose a Hamiltonian model that describes the interaction between a vortex line in superfluid He and the gas of elementary excitations. An equation of irreversible motion…
