Polar transform and local positivity for curves [PDF]
Annales de la Faculté des sciences de Toulouse : Mathématiques, 2020 Using the duality of positive cones, we show that applying the polar transform from convex analysis to local positivity invariants for divisors gives interesting and new local positivity invariants for curves. These new invariants have nice properties similar to those for divisors.

Properties of extragalactic dust inferred from linear polarimetry of Type Ia Supernovae [PDF]
, 2015 Aims: The aim of this paper is twofold: 1) to investigate the properties of extragalactic dust and compare them to what is seen in the Galaxy; 2) to address in an independent way the problem of the anomalous extinction curves reported for reddened Type ...
