[Banach] Abstract of a paper by Mohammed Bachir and Joel Blot

This is an announcement for the paper "A useful lemma for Lagrange multiplier rules in infinite dimension" by Mohammed Bachir and Joel Blot.

Abstract: We give some reasonable and usable conditions on a sequence of norm one in a dual banach space under which the sequence does not converges to the origin in the $w^*$-topology. These requirements help to ensure that the Lagrange multipliers are nontrivial, when we are interested for example on the infinite dimensional infinite-horizon Pontryagin Principles for discrete-time problems.
