An abstract inf-sup problem inspired by limit analysis in perfect plasticity and related applications
Stanislav Sysala, Jaroslav Haslinger, Daya Reddy +1
This work is concerned with an abstract inf-sup problem generated by a bilinear Lagrangian and convex constraints. We study the conditions that guarantee no gap between the inf-sup…

Verifications of primal energy identities for variational problems with obstacles
Sergey Repin, Jan Valdman
We discuss error identities for two classes of free boundary problems generated by obstacles. The identities suggest true forms of the respective error measures which consist of tw…
