Emergent supersymmetry at large N

open access: yesJournal of High Energy Physics
We search for infrared fixed points of Gross-Neveu Yukawa models with matrix degrees of freedom in d = 4 − ε. We consider three models — a model with SU(N) symmetry in which the scalar and fermionic fields both transform in the adjoint representation, a ...

Optimal Contracts for Delegated Order Execution

open access: yesMathematical Finance, EarlyView.
ABSTRACT We determine the optimal affine contract for a client who delegates their order execution to a dealer. Existence and uniqueness are established for general linear price impact dynamics of the dealer's trades. Explicit solutions are available for the model of Obizhaeva and Wang, for example, and a simple gradient descent algorithm is applicable

Locally constant fibrations and positivity of curvature

open access: yesBulletin of the London Mathematical Society, Volume 57, Issue 4, Page 1005-1025, April 2025.
Abstract Up to finite étale cover, any smooth complex projective variety X$X$ with nef anti‐canonical bundle is a holomorphic fibre bundle over a smooth projective variety with trivial canonical class (K‐trivial variety for short) with locally constant transition functions. We show that this result is optimal by proving that any projective fibre bundle

The homological spectrum via definable subcategories

open access: yesBulletin of the London Mathematical Society, Volume 57, Issue 4, Page 1040-1064, April 2025.
Abstract We develop an alternative approach to the homological spectrum of a tensor‐triangulated category through the lens of definable subcategories. This culminates in a proof that the homological spectrum is homeomorphic to a quotient of the Ziegler spectrum.

New Z3 strings

open access: yesPhysics Letters B, 2016
We consider a Yang–Mills–Higgs theory with the gauge group SU(3) broken to its center Z3 by two scalar fields in the adjoint representation and obtain new Z3 strings asymptotic configurations with the gauge field and magnetic field in the direction of ...

A stable difference scheme for the solution of a source identification problem for telegraph-parabolic equations

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы
In the present paper, we construct a first order of accuracy difference scheme for the approximate solution of the inverse problem for telegraph-parabolic equations with an unknown spacewise dependent source term.
