ROUQUIER’S CONJECTURE AND DIAGRAMMATIC ALGEBRA
Forum of Mathematics, Sigma, 2017 We prove a conjecture of Rouquier relating the decomposition numbers in category ${\mathcal{O}}$ for a cyclotomic rational Cherednik algebra to Uglov’s ...

Vanishing and localization of $(d,\frak{b})$-ideal transforms [PDF]
Journal of Mahani Mathematical ResearchLet $R$ be a commutative Noetherian ring, $\!M$ an $\!R$-module and $d$ a non-negative integer. Let $\Sigma$ denote the set of ideals $\frak{I}$ of $R$ such that $\mathrm{dim}(R/\frak{I})\!\leq\!d$.

The Kazhdan-Lusztig conjecture for W-algebras [PDF]
, 1995 The main result in this paper is the character formula for arbitrary irreducible highest weight modules of W algebras. The key ingredient is the functor provided by quantum Hamiltonian reduction, that constructs the W algebras from affine Kac-Moody ...

Moscow Mathematical Journal, 2011 For a finite group $G$, the so-called $G$-Mackey functors form an abelian category $M(G)$ that has many applications in the study of $G$-equivariant stable homotopy. One would expect that the derived category $D(M(G))$ would be similarly important as the "homological" counterpart of the $G$-equivariant stable homotopy category.

Formal deformations and their categorical general fibre
, 2011 We study the general fibre of a formal deformation over the formal disk of a projective variety from the view point of abelian and derived categories. The abelian category of coherent sheaves of the general fibre is constructed directly from the formal ...

Derived equivalences for trigonometric double affine Hecke algebras
Forum of Mathematics, SigmaThe trigonometric double affine Hecke algebra $\mathbf {H}_c$ for an irreducible root system depends on a family of complex parameters c. Given two families of parameters c and $c'$ which differ by integers, we construct the translation ...

Can we repudiate ontology altogether?
Noûs, EarlyView.Abstract Ontological nihilists repudiate ontology altogether, maintaining that ontological structure is an unnecessary addition to our theorizing. Recent defenses of the view involve a sophisticated combination of highly expressive but ontologically innocent languages combined with a metaphysics of features—non‐objectual, complete but modifiable states

Derived Categories of Coherent Sheaves and Triangulated Categories of Singularities
, 2009 In this paper we establish an equivalence between the category of graded D-branes of type B in Landau-Ginzburg models with homogeneous superpotential W and the triangulated category of singularities of the fiber of W over zero.

3D MR Thermometry Using Bi‐Directional Segmented EPI for Transcranial‐Focused Ultrasound
Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2106-2116, April 2026.ABSTRACT Purpose To evaluate the feasibility of replacing clinically utilized 2D thermometry with 3D segmented EPI‐based thermometry with equivalent accuracy, precision, and scan time. Methods A 3D segmented EPI (segEPI) trajectory was modified to allow readouts along both the forward and reverse direction for each phase encoding line, and the sequence
