DESCRIPTION:I will introduce a symmetric monoidal 2-category w
 hose objects are 0-manifolds\, whose 1-morphisms a
 re 1-dimensional smooth cobordisms\, and whose 2-m
 orphisms are Riemann surfaces with boundary and cu
 sps. I will introduce a certain central extension 
 by &#x211D\;&#x208A\; and explain its relevance in
  chiral conformal field theory. Finally\, I will e
 xplain the state of my understanding on the questi
 on of classification of such extensions by &#x211D
 \;&#x208A\;.
