Kontsevich's graph complex, GRT, and the deformation complex of the sheaf of polyvector fields
Vasily Dolgushev, Christopher L. Rogers, Thomas Willwacher
We generalize Kontsevich's construction of L-infinity derivations of polyvector fields from the affine space to an arbitrary smooth algebraic variety. More precisely, we construct…
Characteristic classes in deformation quantization
Thomas Willwacher
In deformation quantization one can associate five characteristic functions to (stable) formality morphisms on cochains and chains and to "two-brane" formality morphisms. We show t…
Operadic Twisting -- with an application to Deligne's conjecture
Vasily Dolgushev, Thomas Willwacher
We study categorial properties of the operadic twisting functor Tw. In particular, we show that Tw is a comonad. Coalgebras of this comonad are operads for which a natural notion o…
Reconstruction of hidden 3D shapes using diffuse reflections
Otkrist Gupta, Andreas Velten, Thomas Willwacher +2
We analyze multi-bounce propagation of light in an unknown hidden volume and demonstrate that the reflected light contains sufficient information to recover the 3D structure of the…
