Extension of convex functions from a hyperplane to a half-space
John M. Ball, Christopher L. Horner
It is shown that a possibly infinite-valued proper lower semicontinuous convex function on has an extension to a convex function on the half-space ${\mathbb R}^n\ti…

Quasistatic nonlinear viscoelasticity and gradient flows
John M. Ball, Yasemin Şengül
We consider the equation of motion for one-dimensional nonlinear viscoelasticity of strain-rate type under the assumption that the stored-energy function is -convex, which allow…
