Mixed methods for the velocity-pressure-pseudostress formulation of the Stokes eigenvalue problem
Felipe Lepe, Gonzalo Rivera, Jesus Vellojin
In two and three dimensional domains, we analyze mixed finite element methods for a velocity-pressure-pseudostress formulation of the Stokes eigenvalue problem. The methods consist…

Displacement-pseudostress formulation for the linear elasticity spectral problem
Daniel Inzunza, Felipe Lepe, Gonzalo Rivera
In this paper we analyze a mixed displacement-pseudostress formulation for the elasticity eigenvalue problem. We propose a finite element method to approximate the pseudostress ten…
