An elementary proof of optimality conditions for linear programming

Sammanfattning: Proving optimality conditions for linear programming is straightforward, if one assumes that the problem is primal nondegenerate. The general case, covering degeneracy, is less straightforward. Traditionally, one makes use of either Farkas' lemma or of the simplex method with some anti-cycling scheme. In this talk, we give an elementary proof of optimality conditions for linear programming, built on a straightforward classical perturbation of the constraints. The proof does not require either the use of Farkas' lemma or the use of the simplex method. As a by-product, we also obtain a proof of Farkas' lemma.

Unmasking the Dark side of the Universe

in C1 on 23 Oct: 17.00-18.00.

Abstract: Over the past decade there has been considerable progress in our understanding of the universe, largely due to the impact technological advances have had on observational cosmology. The detailed understanding of cosmic microwave background anisotropies and the formation of large-scale structure, together with type Ia supernova measurements have allowed cosmologists to constrain the basic parameters of the universe to such an extent, that we now have a model that appears to fit almost all available data - the "Concordance Model". This description of the universe would never have been predicted 30 years ago and might require new physics to explain what we observe. It is just possible that these observations might be pointing towards a break down of Einstein's famous theory on cosmological scales - an exciting prospect! My talk will trace the history of the standard cosmology and will explain how the concordance model has come about and how current and future experiments like the Large Hadron Collider at CERN and the PLANCK satellite will shed light on this new physics.
