Groups of piecewise isometric permutations of lattice points, or Finitary rearrangements of tessellations

Journal of the London Mathematical Society, Volume 106, Issue 3, Page 1663-1724, October 2022., 2022
Abstract Through the glasses of didactic reduction, we consider a (periodic) tessellation Δ$\Delta$ of either Euclidean or hyperbolic n$n$‐space M$M$. By a piecewise isometric rearrangement of Δ$\Delta$ we mean the process of cutting M$M$ along corank‐1 tile‐faces into finitely many convex polyhedral pieces, and rearranging the pieces to a new tight ...

The anomaly that was not meant IIB

Fortschritte der Physik, Volume 70, Issue 1, January 2022., 2022
Abstract Type IIB supergravity enjoys a discrete non‐Abelian duality group, which has potential quantum anomalies. In this paper we explicitly compute these, and present the bordism group that controls them, modulo some physically motivated assumptions.

When is a monotone function cyclically monotone?

Theoretical Economics, Volume 16, Issue 3, Page 853-879, July 2021., 2021
We provide sufficient conditions for a monotone function with a finite set of outcomes to be cyclically monotone. Using these conditions, we show that any monotone function defined on the domain of gross substitutes is cyclically monotone. The result also extends to the domain of generalized gross substitutes and complements.

On topological Hochschild homology of the K(1)‐local sphere

Journal of Topology, Volume 14, Issue 1, Page 258-290, March 2021., 2021
Abstract We compute mod (p,v1) topological Hochschild homology of the connective cover of the K(1)‐local sphere spectrum for all primes p⩾3. This is accomplished using a May‐type spectral sequence in topological Hochschild homology constructed from a filtration of a commutative ring spectrum.

More on Selective Covering Properties in Bitopological Spaces

Journal of Mathematics, Volume 2021, Issue 1, 2021., 2021
In this study, we continue our investigation of selective covering properties in bitopological spaces. We discuss their behaviour under certain kinds of mappings. We also introduce selective versions of the ccc property and the star‐ccc property in bitopological spaces and give few of their relations with other selective properties.

Star-Hurewicz and related properties

Applied General Topology, 2004
We continue the investigation of star selection principles first considered. We are concentrated onto star versions of the Hurewicz covering property and star selection principles related to the classes of open covers which have been recently introduced.

The circle action on topological Hochschild homology of complex cobordism and the Brown–Peterson spectrum

Journal of Topology, Volume 13, Issue 3, Page 939-968, September 2020., 2020
Abstract We specify exterior generators in π∗THH(MU)=π∗(MU)⊗E(λn′∣n⩾1) and π∗THH(BP)=π∗(BP)⊗E(λn∣n⩾1), and calculate the action of the σ‐operator on these graded rings. In particular, σ(λn′)=0 and σ(λn)=0, while the actions on π∗(MU) and π∗(BP) are expressed in terms of the right units ηR in the Hopf algebroids (π∗(MU),π∗(MU∧MU)) and (π∗(BP),π∗(BP∧BP)),

Some remarks on Pixley-Roy hyperspaces

Tạp chí Khoa học Đại học Huế: Khoa học Tự nhiên
In this paper, we study cellular-compact, cellular-Lindel\"of, strongly star-Hurewicz, strongly star-Rothberger, strongly star-Menger spaces on hyperspaces with the Pixley-Roy topology.

Infinity‐operadic foundations for embedding calculus

Journal of Topology, Volume 19, Issue 2, June 2026.
Abstract Motivated by applications to spaces of embeddings and automorphisms of manifolds, we consider a tower of ∞$\infty$‐categories of truncated right modules over a unital ∞$\infty$‐operad O$\mathcal {O}$. We study monoidality and naturality properties of this tower, identify its layers, describe the difference between the towers as O$\mathcal {O}$

Stabilization of Poincaré duality complexes and homotopy gyrations

Journal of the London Mathematical Society, Volume 113, Issue 5, May 2026.
Abstract Stabilization of manifolds by a product of spheres or a projective space is important in geometry. There has been considerable recent work that studies the homotopy theory of stabilization for connected manifolds. This paper generalizes that work by developing new methods that allow for a generalization to stabilization of Poincaré duality ...
