Exterior convexity and classical calculus of variations
We study the relation between various notions of exterior convexity
introduced in Bandyopadhyay-Dacorogna-Sil \cite{BDS1} with the classical
notions of rank one convexity, quasiconvexity and polyconvexity. To this end,
we introduce a projection map, which generalizes the alternating projection for
two-tensors in a new way and study the algebraic properties of this map. We
conclude with a few simple consequences of this relation which yields new
proofs for some of the results discussed in Bandyopadhyay-Dacorogna-Sil
\cite{BDS1}.Comment: The original publication is available at www.esaim-cocv.org

On Aspects of Holographic Thermal QCD at Finite Coupling
Some Physics (obtaining lattice-compatible deconfinement temperature, some
transport coefficients and Einstein's relation) and Mathematics (torsion
classes and supersymmetry) issues pertaining to the delocalized SYZ type IIA
mirror of [1] and its M theory uplift in the MQGP limit of [2], are discussed.Comment: v3: 1+63 pages, LaTeX, title slightly modified, large amounts of
explanatory material added and text rearranged though Results are unchanged,
references added, to appear in NPB (the journal version also includes two
figs excluded in the arxiv version due to size constraints). arXiv admin
