Variation of geometric invariant theory quotients and derived categories [PDF]
Journal für die Reine und Angewandte Mathematik, 2012 We study the relationship between derived categories of factorizations on gauged Landau–Ginzburg models related by variations of the linearization in Geometric Invariant Theory.

A Bordism Viewpoint of Fiberwise Intersections
International Journal of Mathematics and Mathematical Sciences, 2013 We use the geometric data to define a bordism invariant for the fiberwise intersection theory. Under some certain conditions, this invariant is an obstruction for the theory. Moreover, we prove the converse of fiberwise Lefschetz fixed point theorem.

Towards relativistic quantum geometry
Physics Letters B, 2015 We obtain a gauge-invariant relativistic quantum geometry by using a Weylian-like manifold with a geometric scalar field which provides a gauge-invariant relativistic quantum theory in which the algebra of the Weylian-like field depends on observers.

Homological Projective Duality via Variation of Geometric Invariant Theory Quotients [PDF]
, 2013 We provide a geometric approach to constructing Lefschetz collections and Landau-Ginzburg Homological Projective Duals from a variation of Geometric Invariant Theory quotients.

Variation of non-reductive geometric invariant theory [PDF]
Surveys in Differential Geometry, 2017 The wall-and-chamber structure of the dependence of the reductive GIT quotient on the choice of linearisation is well known. In this article, we first give a brief survey of recent results in non-reductive GIT, which apply when the unipotent radical is 'graded'. We then examine the dependence of these non-reductive quotients on the linearisation and an

Non-standard neutrino oscillations: perspective from unitarity triangles
Journal of High Energy Physics, 2021 We formulate an alternative approach based on unitarity triangles to describe neutrino oscillations in presence of non-standard interactions (NSI). Using perturbation theory, we derive the expression for the oscillation probability in case of NSI and ...

Heights and Geometric Invariant Theory [PDF]
Forum Mathematicum, 2000 Let $K$ be a number field, $\OK$ be its ring of integers. We introduce the notion of compactified representation of $GL_N(\OK)$ and, we see how to associate to a hermitian vector bundle $\E$ over $\Spec(\OK)$ and a compactified representation $\T$, a hermitian tensor bundle $\E_T$.

Braneworld cosmological perturbations in teleparallel gravity
Physics Letters B, 2015 In this paper we find the fully gauge invariant cosmological perturbation equations in braneworld teleparallel gravity. In this theory, perturbations are the result of small fluctuations in the pentad field. We derive the gauge invariant 'potentials' for

A perturbation of the geometric spectral sequence in Khovanov homology [PDF]
, 2016 We study the relationship between Bar-Natan's perturbation in Khovanov homology and Szabo's geometric spectral sequence, and construct a link invariant that generalizes both into a common theory.

Journal of Function Spaces, 2018 In this paper, a class of indefinite hypersurfaces and a class of indefinite surfaces generated by timelike curves located in nullcone in 4-dimensional semi-Euclidean space with index 2 are discussed. Using the unfolding theory in singularity theory, the
