Evolution of Axially Symmetric Anisotropic Sources in $f(R,T)$ Gravity [PDF]
, 2015 We discuss the dynamical analysis in $f(R,T)$ gravity (where $R$ is Ricci scalar and $T$ is trace of energy momentum tensor) for gravitating sources carrying axial symmetry.

Enumerative aspects of the Gross-Siebert program [PDF]
, 2014 We present enumerative aspects of the Gross-Siebert program in this introductory survey. After sketching the program's main themes and goals, we review the basic definitions and results of logarithmic and tropical geometry.

Contact Geometry of Hyperbolic Equations of Generic Type [PDF]
, 2008 We study the contact geometry of scalar second order hyperbolic equations in the plane of generic type. Following a derivation of parametrized contact-invariants to distinguish Monge-Ampere (class 6-6), Goursat (class 6-7) and generic (class 7-7 ...

Einstein-Riemann Gravity on Deformed Spaces [PDF]
, 2006 A differential calculus, differential geometry and the E-R Gravity theory are studied on noncommutative spaces. Noncommutativity is formulated in the star product formalism. The basis for the gravity theory is the infinitesimal algebra of diffeomorphisms.

Computers & Mathematics with Applications, 1986 AbstractThe beautiful external forms of crystals are manifestations of their internal structures. These structures, which can be regarded as infinite periodic patterns, are determined by local forces. In this article we discuss symmetry from the “local” point of view.

Symmetry and Symmetry Breaking in Physics: From Geometry to Topology [PDF]
Symmetry, 2021 Symmetry (and group theory) is a fundamental principle of theoretical physics. Finite symmetries, continuous symmetries of compact groups, and infinite-dimensional representations of noncompact Lie groups are at the core of solid physics, particle physics, and quantum physics, respectively.

Geometry-symmetry-free and material-symmetry-guaranteed polariton-induced transparency
iScienceSummary: Plasmon-induced transparency is a classical analogue of electromagnetically induced transparency (EIT). However, its realization and control primarily rely on geometry engineering rather than tuning plasmon polaritons (PPs) themselves, due to ...

Geometric Curvatures of Plane Symmetry Black Hole
Advances in High Energy Physics, 2013 We study the properties and thermodynamic stability of the plane symmetry black hole from the viewpoint of geometry. We find that the Weinhold curvature gives the first-order phase transition at N=1, where N is a parameter of the plane symmetry black ...

Symmetry as tactics of solving mathematical problems
Lietuvos Matematikos Rinkinys, 2012 The article explores symmetry as tactics in solving various mathematical problems. Although in Mathematics curriculum while learning about Geometry, symmetry is taught and simple straightforward exercises are solved, it is argued that the application of ...
