Scalar Curvature Rigidity and Higher Index Theory

Thomas Tony

Llarull proved in the late '90s that the round n-sphere is area-extremal, meaning that one cannot simultaneously increase both its scalar curvature and its metric. Goette and Semmelmann generalized...

Cosmological solutions to the semiclassical Einstein equation with Minkowski-like vacua

Nicolai Rothe (TU Berlin)

We will discuss some newly found solutions to the full massless semiclassical Einstein equation (SCE) in a cosmological setting (with Λ=0).

After a short introduction to the relevant notions, we...

Spectral flow of twisted Dirac operators

Remo Ziemke

This thesis generalizes Getzler's spectral flow formula for twisted Dirac operators to arbitrary twisting bundles and 1-parameter-families of connections. The formula proved by Getzler states that

Rough Geometric Integration

Harprit Singh (Wien) (online)

Combining ideas from Whitney’s geometric integration theory and rough analysis, we introduce spaces of rough differential \(k\) forms on \(d\)-manifolds which are formally given by
\(f = \sum _I...
