We give a bordered extension of involutive HF-hat and use it to give an
algorithm to compute involutive HF-hat for general 3-manifolds. We also explain
how the mapping class group action on HF-hat can be computed using bordered

In this article we investigate a monoid of smooth mappings on the space of
arrows of a Lie groupoid and its group of units. The group of units turns out
to be an infinite-dimensional Lie group which is regular in the sense of
Milnor. Furthe...

Recently, Segal constructed a derived equivalence for an interesting 5-fold
flop that was provided by Abuaf. The aim of this article is to add some results
for the derived equivalence for Abuaf's flop. Concretely, we study the
equivalence f...

We consider an ecology model in which the population is structured by a
spatial variable and a phenotypic trait. The model combines a parabolic
operator on the spatial variable with a kinetic operator on the trait variable.
We prove the exi...

In this paper, we propose a SaaS service which prevents shoplifting using
image analysis and ERP. In Japan, total damage of shoplifting reaches 450
billion yen. Based on cloud and data analysis technology, we propose a

The g-theorem is a momentous result in combinatorics that gives a complete
numerical characterization of the face numbers of simplicial convex polytopes.
The g-conjecture asserts that the same numerical conditions given in the
g-theor...
Strongly Dependent Ordered Abelian Groups and Henselian Fields

Strongly dependent ordered abelian groups have finite dp-rank. They are
precisely those groups with finite spines and ∣{p prime:[G:pG]=∞}∣<∞. We apply this to show that if K is a
strongly dependent field, then (K,v)...

We study the post-critical set of a class of holomorphic systems with an
irrationally indifferent fixed point. We prove a trichotomy for the topology of
the post-critical set based on the arithmetic of the rotation number at the
fixed point...
