Alterations of the gravity Lagrangian introduced in modified torsion gravity theories---also referred to as $f(T)$ gravity---allows for an accelerated expansion in a matter dominated Universe. In this framework, the cosmic speed up is driven by an effective `torsion fluid'. Besides the background evolution of the Universe, structure formation is also modified because of a time dependent effective gravitational constant. Here, we investigate the imprints of $f(T)$ gravity on galaxy clustering…

Toward a concordance teleparallel Cosmology I: Background Dynamics
Assuming the universe to be spatially flat with homogeneous and isotropic background, we study the cosmological viability of the infrared corrected $f(T)=T e^{\beta T_0/T}$ teleparallel gravity in
Toward a concordance teleparallel cosmology. Part I. Background dynamics
Assuming a spatially flat universe, we study the cosmological viability of an infrared corrected teleparallel gravity model, which accounts for late acceleration by weakening gravity at later times
Dynamical systems approach and generic properties of $f(T)$ cosmology
We present a systematic analysis of the dynamics of flat Friedmann-Lema\^{i}tre-Robertson-Walker cosmological models with radiation and dust matter in generalized teleparallel $f(T)$ gravity. We show
Weakly dynamic dark energy via metric-scalar couplings with torsion
We study the dynamical aspects of dark energy in the context of a non-minimally coupled scalar field with curvature and torsion. Whereas the scalar field acts as the source of the trace mode of
Can f(T) gravity resolve the H0 tension?
Motivated by the discrepancy in measurements of H0 between local and global probes, we investigate whether teleparallel gravities could be a better model to describe the present-day observations or
Repulsive gravitational force and quintessence field in f(T) gravity: How anisotropic compact stars in strong energy condition behave
Recently literature is found to be enriched with studies related to anisotropic behaviors of different compact stars in the background of [Formula: see text] gravity in different energy conditions.
FRW in quadratic form of f(T) gravitational theories
We derive asymptote solution of a homogeneous and isotropic universe governed by the quadratic form of the field equation of f(T) gravity. We explain how the higher order of the torsion can provide
Cosmological dark sector from a mimetic–metric–torsion perspective
We generalize the basic theory of mimetic gravity by extending its purview to the general metric-compatible geometries that admit torsion, in addition to curvature. This essentially implies
Toward a concordance teleparallel cosmology. Part II. Linear perturbation
Late time cosmic acceleration may be achieved by modifying gravity on large scales. This should also have consequences on the evolution of perturbations. We thus extend our study of exponential
Study of anisotropic compact stars with quintessence field and modified chaplygin gas in f(T) gravity
In this work, we get an idea of the existence of compact stars in the background of f(T) modified gravity where T is a scalar torsion. We acquire the equations of motion using anisotropic property

It is still unknown whether there are families of tight knots whose lengths grow faster than linearly with crossing numbers, but the largest power has been reduced to 3/z, and some other physical models of knots as flattened ropes or strips which exhibit similar length versus complexity power laws are surveyed.
The Theory of Probability
This book is a searching analysis of the fundamental principles of the theory of probability and of the particular judgments involved in its application to concrete problems and is in agreement with the views expressed by Dr. Wrinch and the present reviewer.
