DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Freemath/33/
 ">Polarized Weinstein manifolds and their positive arboreal skeleta</a>\nb
 y Daniel Álvarez-Gavela as part of Free Mathematics Seminar\n\n\nAbstract
 \nThe goal of this talk is to give a geometric introduction to arboreal si
 ngularities\, as well as to the distinguished subclass of *positive* arbor
 eal singularities\, and to state precisely the theorem joint with Y. Elias
 hberg and D. Nadler that a Weinstein manifold admits a global field of Lag
 rangian planes if and only if the Weinstein structure can be deformed so t
 hat the skeleton becomes positive arboreal. In particular it follows that 
 complete intersections in complex affine space can be arborealized.\n
