The aim of this paper is to introduce and give preliminary investigation of ∂-partial-locally Compact spaces. Locally Compactness and ∂-partial-locally Compactness are independent of each other. Every locally Compact Hausdorff space is ∂-partial-locally Compact. But the converse is not true even though it be Hausdorff. ∂-partial-locally Compactness is a topological property. ∂-partial-locally Compactness is not preserved by the product topology.

Let (M,g) be a Compact immersed hypersurface of (Rn+1,<,>), l1 the first nonzero eigenvalue, a the mean curvature, P the support function, A the shape operator, vol(M) the volume of M, and S the scalar curvature of M. In this paper, we established some eigenvalue inequalities and proved the above.1/n òM \\A\\2 P2DV ³ </span></p>M  a2 P2 dV. 2 òM a2 P2 dV ³ 1/n (n-1) òM sp2 dV.If the scalar curvature S and the first nonzero eigenvalue l1 staisfy S= l1 (N-1), than òM [a2 - l1/n] p2 dv³ 0, 4) Suppose that the Ricci curvature of M is bounded below by a positive constant k.

This is a survey on some recent progress in homogeneous Finsler geometry. Three topics are discussed, the classi, cation of positively curved homogeneous Finsler spaces, the geometric and topological properties of homogeneous Finsler spaces satisfying K ,0 and the (FP) condition, and the orbit number of prime closed geodesics in a Compact homogeneous Finsler manifold. These topics share the same similarity that the same rank inequality, i. e., rankG ,rankH +1 for G=H with Compact G and H, plays an important role. In this survey, we discuss in each topic how the rank inequality is proved, explain its importance, and summarize some relevant results.

We call G to be an α,-coset group, if it contains a proper α,-invariant normal subgroup N such that Nxα,= {xg | g ∈,G}, for some automorphism α,of G and any x ∈,G\N. Clearly, if α,is identity automorphism of G, one obtains the notion of con-cos groups, which was first introduced by Muktibodh in 2006. In the present article, we discuss some properties of the new notion. Also, we introduce the concept of α,-Camina groups and give its connection with the groups of property P, where P is the class of all finite groups such that their α,-centres are the same as α,-commutator subgroups of order p.

We study the double cosets of a Lie group by a Compact Lie subgroup. We show that a Weil formula holds for double coset Lie hypergroups and show that certain representations of the Lie group lift to representations of the double coset Lie hypergroup. We characterize smooth (analytic) vectors of these lifted representations.

In this paper, we give the characterization of some classes of Compact operators given by matrices on the normed sequence space rqp (Bm), which is a special case of the paranormed Riesz Bm-difference sequence space rq (p, Bm). For this purpose, we apply the Hausdorff measure of nonCompactness and use some results.

For suitable Banach spaces X and Y with Schauder decompositions and a suitable closed subspace M of some Compact operator space from X to Y, it is shown that the strong Banach-Saks-ness of all evaluation operators on M is a sufficient condition for the weak Banach-Saks property of M, where for each xÎX and y*ÎY*, the evaluation operators on M are defined by fx (T)= Tx and yy* (T)= T*y*.

We show that typical elements of the set of continuous functions from a Compact differentiable manifold M to Rn are nowhere differentiable. Then, we study the box dimensions of typical elements in the set of images of M in Rn.
