 >Compact moduli of K3 surfaces and tropical spheres with 24 singular point
 s</a>\nby Valery Alexeev (University of Georgia) as part of Geometria em L
 isboa (IST)\n\n\nAbstract\nI will talk about geometric compactifications o
 f moduli spaces of K3 surfaces\, similar in spirit to the Deligne-Mumford 
 moduli spaces of stable curves. Constructions borrow ideas from the tropic
 al and integral-affine geometry and mirror symmetry. The main result is th
 at in many common situations there exists a geometric compactification whi
 ch is toroidal\, and many of these compactifications can be described expl
 icitly using tropical spheres with 24 singular points. Much of this talk i
 s based on the joint work with Philip Engel.\n
