DESCRIPTION:Title: Global group laws and the equivariant Quillen theorem\nby Markus Ha
usmann (Universität Bonn) as part of UCPH Algebra/Topology seminar\n\n\nA
bstract\nQuillen's theorem that the complex bordism ring carries the unive
rsal formal group law is a fundamental result in stable homotopy theory. I
n this talk I will discuss equivariant versions of this theorem\, both ove
r a fixed abelian compact Lie group and in a global equivariant setting.\n

DESCRIPTION:Title: Combinatorial homotopy theory for operads\nby Jovana Obradovic (Ser
bian Academy of Sciences and Arts) as part of UCPH Algebra/Topology semina
r\n\n\nAbstract\nWe introduce an explicit combinatorial characterization o
f the minimal model of the coloured operad encoding non-symmetric operads.
In our description\, the spaces of operations are defined in terms of hyp
ergraph polytopes and the composition structure generalizes the one of Sta
sheff's associahedra operad.\n
