On Infinitesimal Projective Transformations of the Tangent Bendle with the Complete Lift of a Finsler Metric [PDF]
, 2017 Let (M,g) be a Finsler manifold and TM0 its slit tangent bundle with the complete lift metric ~g.In this paper we prove that every infinitesimal complete lift projective transformation on (TM0,~g), is an infinitesimal affine transformation. Moreover, if (

Toward a Definition of Complexity for Quantum Field Theory States. [PDF]
Physical Review Letters, 2017 We investigate notions of complexity of states in continuous many-body quantum systems. We focus on Gaussian states which include ground states of free quantum field theories and their approximations encountered in the context of the continuous version ...

On infinitesimal transformations of Weyl manifolds [PDF]
AIP Conference Proceedings, 2019 A Weyl manifold is a conformal manifold equipped with a torsion free connection preserving the conformal structure. In order to make computations in a conformal gauge invariant way, it is better to work with weighted tensors and Weyl’s covariant derivative which will be called prolonged covariant derivative.

Stability of Spherical Nuclei in the Inner Crust of Neutron Stars
Particles, 2022 Neutron stars are the densest objects in the Universe. In this paper, we consider the so-called inner crust—the layer where neutron-excess nuclei are immersed in the degenerate gas of electrons and a sea of quasi-free neutrons.

A Finite Strain Constitutive Model for Martensitic Transformation in Shape Memory Alloys Based on Logarithmic Strain. [PDF]
, 2017 Shape Memory Alloys (SMAs) are materials with the ability to recover apparently permanent deformation under specific thermomechanical loading. The majority of constitutive models for SMAs are developed based on the infinitesimal strain theory.

*-Ricci soliton on (κ, μ)′-almost Kenmotsu manifolds
Open Mathematics, 2019 Let (M, g) be a non-Kenmotsu (κ, μ)′-almost Kenmotsu manifold of dimension 2n + 1. In this paper, we prove that if the metric g of M is a *-Ricci soliton, then either M is locally isometric to the product ℍn+1(−4)×ℝn or the potential vector field is ...

Karpatsʹkì Matematičnì Publìkacìï, 2023 The goal of this paper is to find some important Einstein manifolds using conformal Ricci solitons and conformal Ricci almost solitons. We prove that a Kenmotsu metric as a conformal Ricci soliton is Einstein if it is an $\eta$-Einstein or the potential ...

Tensor models and hierarchy of n-ary algebras [PDF]
, 2011 Tensor models are generalization of matrix models, and are studied as models of quantum gravity. It is shown that the symmetry of the rank-three tensor models is generated by a hierarchy of n-ary algebras starting from the usual commutator, and the 3-ary

On Infinitesimal Increase of Volumes of Morphological Transforms [PDF]
Mathematika, 2006 Summary: Let \(B\) (``black'') and \(W\) (``white'') be disjoint compact test sets in \(\mathbb{R}^d\), and consider the volume of all its simultaneous shifts keeping \(B\) inside and \(W\) outside a compact set \(A\subset\mathbb{R}^d\). If the union \(B\cup W\) is rescaled by a factor tending to zero, then the rescaled volume converges to a value ...
