DESCRIPTION:Organisers\nRIMANYI Richard (University of North Carolina).\nS
 ZENES Andras (Université de Genève).\nGlobal singularity theory is part 
 of enumerative geometry concerned with universal polynomials expressing fu
 ndamental cohomology classes of multi-singularity submanifolds. The field 
 was founded by René Thom in the 50’s\, and saw some important developme
 nts in the past decade. Recent works show that the universal polynomials a
 re related to interpolation theory in several variables\, quivers\, Landwe
 ber-Novikov classes\, K-theory and counting curves on surfaces.\nGlobal si
 ngularity theory\, when applied to maps between parameter or moduli spaces
  of algebraic objects\, enumerates singular objects in a family. In partic
 ular\, It could be used to count singular hypersurfaces in the style of th
 e Gottsche conjecture and its variants.\nThe goal of the workshop is to br
 ing together experts in several fields to compare the global singularity t
 heory approach with other effective tools of enumerative geometry coming f
 rom classical algebraic geometry and tropical geometry.
