DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OATS/11/">El
 liptic cohomology of level n</a>\nby Lennart Meier (Utrecht) as part of On
 line algebraic topology seminar\n\n\nAbstract\nElliptic genera have played
  an important role in algebraic topology and algebraic geometry since the 
 1980s. To every almost-complex manifold they associate a modular form for 
 the congruence subgroups $\\Gamma_1(n)$. More recently\, elliptic cohomolo
 gy theories have been built that are natural targets of elliptic genera fo
 r families. I will give an overview of these theories and report in partic
 ular on certain $C_2$-equivariant refinements.\n
