Compactifications of strata of differentials

Bulletin of the London Mathematical Society, EarlyView.
Abstract In this informal expository note, we quickly introduce and survey compactifications of strata of holomorphic 1‐forms on Riemann surfaces, that is, spaces of translation surfaces. In the last decade, several of these have been constructed, studied, and successfully applied to problems.

Maximal symplectic torus actions

Bulletin of the London Mathematical Society, EarlyView.
Abstract There are several different notions of maximal torus actions on smooth manifolds, in various contexts: symplectic, Riemannian, complex. In the symplectic context, for the so‐called isotropy‐maximal actions, as well as for the weaker notion of almost isotropy‐maximal actions, we give classifications up to equivariant symplectomorphism.

Topological phase transitions in glassy quantum matter

Physical Review Research, 2020
Amorphous systems have rapidly gained attention as promising platforms for topological matter. In this work, we establish a scaling theory of amorphous topological phase transitions driven by the density of lattice points in two dimensions.

Farber's Lipogranulomatosis: Multimodal Therapy With Tocilizumab and Consolidative HSCT Improves Assessment, and Long‐Term Outcome

JIMD Reports, Volume 66, Issue 5, September 2025.
ABSTRACT Farber's lipogranulomatosis (FL) is an autosomal recessive lipid storage disorder, arising as a consequence of genetic acid ceramidase deficiency. Clinically, it presents as severe arthritis, voice hoarseness, and widespread, painful subcutaneous nodules (SCN).

The large-N partition function for non-parity-invariant Chern-Simons-matter theories

Journal of High Energy Physics, 2020
We extend the Fermi gas approach to a class of ABJM-like necklace quiver theories without parity invariance. The resulting partition function on S 3 retains the form of an Airy function, but now includes a phase that scales as Nk in the large-N limit ...

On the symmetry TFT of Yang-Mills-Chern-Simons theory [PDF]

Journal of High Energy Physics
Three-dimensional Yang-Mills-Chern-Simons theory has the peculiar property that its one-form symmetry defects have nontrivial braiding, namely they are charged under the same symmetry they generate, which is then anomalous.

Fermionic CFTs from topological boundaries in abelian Chern-Simons theories

Journal of High Energy Physics
A quantum field theory is referred to as bosonic (non-spin) if its physical quantities are independent of the spacetime spin structure, and as fermionic (spin) if they depend on it.

Chern–Simons classes for a superconnection

Expositiones Mathematicae, 2009
AbstractIn this note we define the Chern–Simons classes of a flat superconnection, D+L, on a complex Z/2Z-graded vector bundle E on a manifold such that D preserves the grading and L is an odd endomorphism of E. As an application, we obtain a definition of Chern–Simons classes of a (not necessarily flat) morphism between flat vector bundles on a smooth

Tian invariant on generalized Calabi manifold

Arab Journal of Mathematical Sciences, 2015
In this article we calculate the Tian invariant on some Fano manifolds. These manifolds generalize those introduced by the first author in collaboration with Pascal Cherrier, in Ben Abdesselem and Cherrier (2009 [1]).

Intersection theory and Chern classes in Bott–Chern cohomology

Arkiv för Matematik, 2023
In this article, we investigate an axiomatic approach introduced by Grivaux for the study of rational Bott-Chern cohomology, and use it in that context to define Chern classes of coherent sheaves. This method also allows us to derive a Riemann-Roch-Grothendieck formula for a projective morphism between smooth complex compact manifolds.
