Title: An introduction to John-Nirenberg spaces and recent results featuring vanishing subspaces and maximal functions
Abstract: The space of functions of bounded mean oscillation BMO was first defined by John and Nirenberg in 1961, and it is an essential function space in harmonic analysis. The John-Nirenberg space JNp was first defined in the same paper and it is also related to oscillations, but it has not been studied as much as BMO. In this talk I will first present the definition and some of

Symmetry and enumerative geometry
馃搫 ABSTRACT /听R脡SUM脡听
Enumerative geometry is the art and science of counting geometric things, for instance there are 27 lines on a cubic surface, 28 bitangents to a planar quartic, etc. Enumerative questions first appeared in ancient Greek geometry, and flourished during the French school of projective geometry in the 19th century. Today this discipline enjoys wide-reaching connections throughout mathematics and physics.
