F-Supplemented Modules
Let R be a ring, let M be a left R-module, and let U,V,F be submodules of M with F proper. We call V an F-supplement of U in M if V is minimal in the set F⊆X⊆M such that U+X=M, or equivalently, F⊆V, U+V=M and U∩V is...

Finite torsors over strongly $F$-regular singularities
We investigate finite torsors over big opens of spectra of strongly $F$-regular germs that do not extend to torsors over the whole spectrum. Let $(R,\mathfrak{m},k)$ be a strongly $F$-regular $k$-germ where $k$ is an...

Dynamic Properties of the Dynamical System Sfnm(X), Sfnm(F))
<p>Let X be a continuum and let n be a positive integer. We consider the hyperspaces F<sub>n</sub>(X) and SF<sub>n</sub>(X). If m is an integer such that n &gt; m ≥ 1, we consider the...

Lrs Bianchi Type-I Universe with Anisotropic Dark Energy and Special Form of Deceleration Parameter in F (R, T) Gravity
In this paper, LRS Bianchi type-I space-time is considered in the presence of perfect fluid source in the frame work of  gravity (Harko et al. in Phys.Rev. D 84:024020, 2011) where is an arbitrary function of Ricci...

On Monotonic Bijections on Subgroups of R
We show that for any continuous monotonic  bijection $f$ on a $\sigma$-compact subgroup  $G\subset \mathbb R$ there exists a binary operation $+_f$ such that $\langle G, +_f\rangle$  is a topological group topologically...

Linearized f(R) gravity: Gravitational radiation and Solar System tests
We investigate the linearized form of metric f ( R ) -gravity, assuming that f ( R ) is analytic about R = 0 so it may be expanded as f ( R ) = R + a 2 R 2 / 2 + … . Gravitational radiation is modified, admitting an extra mode...

Aspects of Cosmological Expansion InF(R) Gravity Models
We study cosmological expansion in F(R) gravity using the trace of the field equations. High frequency oscillations in the Ricci scalar, whose amplitude increases as one evolves backward in time, have been predicted in recent...

Ultraviolet Properties of F(R)-Gravity
We discuss the existence and properties of a nontrivial fixed point in f(R)-gravity, where f is a polynomial of order up to six. Within this seven-parameter class of theories, the fixed point has three...

On the Role of the Weather in the Deaths of R. F. Scott and His Companions
Robert Falcon Scott and his companions reached the South Pole in January of 1912, only to die on their return journey at a remote site on the Ross Ice Shelf, about 170 miles from their base camp on the coast. Numerous...
