Hypersurface-Homogeneous Cosmological Models with Matter and Dark Energy

Shri Ram

In this paper: We have presented exact solutions of Einstein field equations for a hypersurface-homogeneous space time in the presence of a perfect fluid with constant EoS parameter. One solution corresponds to a co...

Matrix Characterization for the Manifold of Euclidean Inner Products of 2-Dimensional Torus

Mohammad Reza Farhangdoost

In this paper: In this paper we study the manifold of all Euclidean inner products of the 2-dimensional torus and we find a representation of its elements by matrices theory.

The Behavior of Spatially Homogeneous and Inhomogeneous Autocatalysis System at Infinity

M. Karimi Amaleh

In this paper: This paper is devoted to the study of a two dimensional spatially homogeneous and inhomogeneous autocatalysis dynamical system. Using the infinite singularity theory and projecting on Poincare hemisph...

Lifting Theorem Concerning Distality on a Fibre Bundle

S. Panda

In this paper: In this note we have proved the lifting properties on fibre bundle W under skew product flow π and established that if bounded solutions are positively uniformly stable then a π–invariant subset of W...

Explicit Estimates on Some Nonlinear Integral Inequalities in Two Independent Variables on Time Scales and Applications

In this paper: The main objective in this paper is to investigate some nonlinear integral inequalities in two independent variables on time scales. The obtained inequalities can be used as handy tools to study the p...

Homology of a Type of Pentahedron

Buddhadev Pal

In this paper: In this paper we find out the homology of a type of pentahedron with five vertices, and have shown that it is analogous with the homology of a chain complex, 0 →Rundefined→Rundefined→Rundefined→ 0 and...

Topological Limits and ω-Limit Sets of the Dendrite Maps

In this paper: Let (X, d) be a metric space and f be a continuous map from X to X. Denote by ω(f) and P(f) the ω-limit set and the set of periodic points of f, respectively. It is well known that for an interval map...
