Quite a number of Z2n\mathbb{Z}_2^n-gradings, n2n\geq 2, appear in Physics and in Mathematics. The corresponding sign rules are given by the `scalar product' of the involved Z2n\mathbb{Z}_2^n-degrees. The new theory exhibits challenging differences with the classical one: nonzero degree even coordinates are not nilpotent…

Smooth Z2n\mathbb{Z}_2^n-supermanifolds have been introduced and studied recently. The corresponding sign rule is given by the "scalar product" of the involved Z2n\mathbb{Z}_2^n-degrees. It exhibits interesting changes in comparison with the sign rule using the parity of the total degree. With the new rule, nonzero degre…

Let M=(M,OM)\mathcal M= (M,\mathcal O_\mathcal M) be a smooth supermanifold with connection \nabla and Batchelor model OMΓΛE\mathcal O_\mathcal M\congΓ_{ΛE^\ast}. From (M,)(\mathcal M,\nabla) we construct a connection on the total space of the vector bundle EME\to{M}. This reduction of \nabla is well-defined independently of …

In LM, we proved a family version of the famous Witten rigidity theorems and several family vanishing theorems for elliptic genera. In this paper, we gerenalize our theorems LM in two directions. First we establish a family rigidity theorem for the Dirac operator on loop space twisted by general positive energy loop gr…

The paper explains the topological origin of the distinction between incidence theorems over division rings and fields.

problem Understanding the distinction between incidence theorems over division rings and fields.
method Extending the surface-graph approach to noncommutative settings, the paper analyzes the topological properties of graphs embedded on surfaces of different genera.
result Theorems associated with graphs on the sphere hold over any division ring, while those on surfaces of positive genus typically hold only if the ground ring is a field.

INT benchmark tests theorem proving agents' ability to generalize to unseen theorems.

problem Evaluating theorem proving agents' ability to generalize to unseen theorems.
method INT benchmark based on a theorem generation and proof procedure with adjustable knobs for measuring 6 types of generalization.
result MCTS can help agents prove new theorems.

A homological selection theorem for C-spaces, as well as, a finite-dimensional homological selection theorem is established. We apply the finite-dimensional homological selection theorem to obtain fixed-point theorems for usco homologically UV^n set-valued maps.

Theorem converse to Jordan's curve theorem says that {\it if a compact set KK has two complementary domains in R2R^{2}, from each of which it is at every point accessible, it is a simple closed curve}. We show that the requirement of this theorem that {\it all} points of KK were accessible from {\it both} complementa…
