The W(E6)$W(E_6)$‐invariant birational geometry of the moduli space of marked cubic surfaces

open access: yesMathematische Nachrichten, Volume 297, Issue 7, Page 2639-2666, July 2024.
Abstract The moduli space Y=Y(E6)$Y = Y(E_6)$ of marked cubic surfaces is one of the most classical moduli spaces in algebraic geometry, dating back to the nineteenth‐century work of Cayley and Salmon. Modern interest in Y$Y$ was restored in the 1980s by Naruki's explicit construction of a W(E6)$W(E_6)$‐equivariant smooth projective compactification Y¯$

A new method of smoothness‐constrained magnetotelluric modelling with the utility of Pareto‐optimal multi‐objective particle swarm optimization

open access: yesGeophysical Prospecting, Volume 72, Issue 5, Page 1985-2004, June 2024.
Abstract Particle swarm optimization, one of the modern global optimization methods, is attracting widespread interest because it overcomes the difficulties of conventional inversion techniques, such as trapping at a local minimum and/or initial model dependence.

Conjectures for Cutting Pizza with Coxeter Arrangements

open access: yesExperimental Mathematics
We are interested in conjecturing the sign of the pizza quantity P(H,B(a,R)) for the irreducible Coxeter arrangements H of type A_n, where n=2,3 bmod 4, and type D_n, where n is odd. Our approach is to express the pizza quantity in terms of the pizza quantity of subarrangements known as 2-structures, and we obtain the first non-zero term in the ...

Equivariant perverse sheaves on Coxeter arrangements and buildings [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2019
When $W$ is a finite Coxeter group acting by its reflection representation on $E$, we describe the category ${\mathsf{Perv}}_W(E_{\mathbb C}, {\mathcal{H}}_{\mathbb C})$ of $W$-equivariant perverse sheaves on $E_{\mathbb C}$, smooth with respect to the stratification by reflection hyperplanes.

Bases of the contact-order filtration of derivations of Coxeter arrangements [PDF]

open access: yesProceedings of the American Mathematical Society, 2005
In a recent paper, we constructed a basis for the contact-order filtration of the module of derivations on the orbit space of a finite real reflection group acting on an ℓ
