Hypercubical manifolds in homotopy type theory
Homotopy type theory is a logical setting in which one can perform geometric constructions and proofs in a synthetic way. Namely, types can be interpreted as spaces up to homotopy, and proofs as homotopy invariant constructions. In this context, we introduce a type which corresponds to the hypercubical manifold, a space first introduced by Poincaré in 1895. Its importance stems from the fact that it provides an approximation of the group Q of quaternionic units, in the sense of being the first…

Homotopy type of complements of fiber-type curves
In this note we study the homotopy type of the complement of a plane projective curve of fiber-type. Roughly speaking, a curve of fiber-type is a finite union of fibers of a pencil. Under some restrictions, a full description of their homotopy type is given. In the context of fiber-type curves, we also partially answer in the positive a question originally posed by Libgober on the homotopy type of complements of plane curves, namely, whether or not the homotopy type of a curve complement is det…

Quadratic Corrections to the Higher-Spin Equations by the Differential Homotopy Approach
The recently proposed differential homotopy approach to the analysis of nonlinear higher spin theory is developed. The Ansatz is extended to the form applicable in the second order of the perturbation theory and general star-multiplication formulae are derived. The relation of the shifted homotopy and differential homotopy formalisms is worked out. Projectively-compact spin-local quadratic (anti)holomorphic vertices in the one-form sector of higher-spin equations are obtained within the differe…

Learning Dexterous Object Handover
Object handover is an important skill that we use daily when interacting with other humans. To deploy robots in collaborative setting, like houses, being able to receive and handing over objects safely and efficiently becomes a crucial skill. In this work, we demonstrate the use of Reinforcement Learning (RL) for dexterous object handover between two multi-finger hands. Key to this task is the use of a novel reward function based on dual quaternions to minimize the rotation distance, which outp…

On Fico's Lemmata and the Homotopy Type of Certain Gyrations

On Fico's Lemmata and the Homotopy Type of Certain Gyrations
We undertake to determine the homotopy type of gyrations of sphere products and of connected sums, thereby generalising results known in earlier literature as ''Fico's Lemmata'' which underpin gyrations in their original formulation from geometric topology. We provide applications arising from recasting these results into the modern homotopy theoretic setting.

Berliner Bildungsverwaltung will kein Handyverbot, setzt auf Eigenverantwortung
In einigen Bundesländern wird das Schulgesetz für Handyverbote angepasst, in Berlin wird es den Schulen überlassen, wie sie mit der Streitfrage umgehen.
