Graph Coverings for Investigating Non Local Structures in Proteins, Music and Poems

open access: yesSci, 2021
We explore the structural similarities in three different languages, first in the protein language whose primary letters are the amino acids, second in the musical language whose primary letters are the notes, and third in the poetry language whose ...

Some aspects of reconstruction using a scalar field in f (T ) Gravity [PDF]

open access: yes, 2017
General relativity characterizes gravity as a geometric property exhibited on spacetime by massive objects while teleparallel gravity achieves the same results, at the level of equations, by taking a torsional perspective of gravity.

Closing Gaps in Geometrically Frustrated Symmetric Clusters: Local Equivalence between Discrete Curvature and Twist Transformations

open access: yesMathematics, 2018
In geometrically frustrated clusters of polyhedra, gaps between faces can be closed without distorting the polyhedra by the long established method of discrete curvature, which consists of curving the space into a fourth dimension, resulting in a ...

Stochastic gravity: beyond semiclassical gravity [PDF]

open access: yesJournal of Physics: Conference Series, 2007
The back-reaction of a classical gravitational field interacting with quantum matter fields is described by the semiclassical Einstein equation, which has the expectation value of the quantum matter fields stress tensor as a source. The semiclassical theory may be obtained from the quantum field theory of gravity interacting with N matter fields in the

Duality-Symmetric Approach to General Relativity and Supergravity [PDF]

open access: yes, 2006
We review the application of a duality-symmetric approach to gravity and supergravity with emphasizing benefits and disadvantages of the formulation. Contents of these notes includes: 1) Introduction with putting the accent on the role of dual gravity ...

The Unexpected Fractal Signatures in Fibonacci Chains

open access: yesFractal and Fractional, 2019
In this paper, a new fractal signature possessing the cardioid shape in the Mandelbrot set is presented in the Fourier space of a Fibonacci chain with two lengths, L and S, where L / S = ϕ . The corresponding pointwise dimension is 1.7.

Dual little strings from F-theory and flop transitions

open access: yesJournal of High Energy Physics, 2017
A particular two-parameter class of little string theories can be described by M parallel M5-branes probing a transverse affine A N − 1 singularity. We previously discussed the duality between the theories labelled by (N, M) and (M, N).

Square gravity [PDF]

open access: yesPhysics Letters B, 1995
We simulate the Ising model on dynamical quadrangulations using a generalization of the flip move for triangulations with two aims: firstly, as a confirmation of the universality of the KPZ/DDK exponents of the Ising phase transition, worthwhile in view of some recent surprises with other sorts of dynamical lattices; secondly, to investigate the ...
