Some homotopy coherent finite group actions on spheres

Manuel Krannich, Oscar Randal-Williams

We provide some examples of homotopy coherent smooth finite group actions on spheres which do not arise from strict actions.

Diffeomorphisms of discs and the second Weiss derivative of BTop(-)

Manuel Krannich, Oscar Randal-Williams

We compute the rational homotopy groups in degrees up to approximately d of the group of diffeomorphisms of a closed d-dimensional disc fixing the boundary. Based on…

Framed configuration spaces and exotic spheres

Manuel Krannich, Alexander Kupers, Fadi Mezher

We determine when an exotic sphere of dimension can be detected through the homotopy type of its truncated Disc-presheaf. The latter records the diagram o…

Isoparametric foliations and bounded geometry

Manuel Krannich, Alexander Lytchak, Marco Radeschi

We prove that there are only finitely many isoparametrically foliated closed connected Riemannian manifolds with bounded geometry, fixed dimension , and finite fundamental…

Infinity-operadic foundations for embedding calculus

Manuel Krannich, Alexander Kupers

Motivated by applications to spaces of embeddings and automorphisms of manifolds, we consider a tower of -categories of truncated right-modules over a unital -opera…

Two remarks on spaces of maps between operads of little cubes

Geoffroy Horel, Manuel Krannich, Alexander Kupers

We record two facts on spaces of derived maps between the operads of little -cubes. Firstly, these mapping spaces are equivalent to the mapping spaces between the non-unit…
