On a Riemannian almost product manifold, the notion of a componentwise conformal vector field is introduced and several examples are exhibited. We show that this class of vector fields is a conformal invariant. For a compact manifold, a Bochner type integral formula for the Ricci tensor on such vector fields is obtained. Then, integral inequalities which link a curvature condition with the exis...

In the present paper, $P-$distributional convergence which is defined by power series method has been introduced. We give equivalent expressions for of spliced sequences. Moreover, a bounded $\infty$-spliced sequence via represented in terms Bochner integral Banach spaces.

A nonlinear stochastic integral equation of the Hammerstein type in the form x(t; c) = h(t; co) + f k(t, s; co)f (s, x(s; co)) dy (s) is studied where t E S, a v-finite measure space with certain properties, co E Q, the supporting set of a probability measure space (Q, A, P), and the integral is a Bochner integral. A random solution of the equation is defined to be a second order vector-valued ...

A Kähler metric is said to be Bochner-Kähler if its Bochner curvature vanishes. This is a nontrivial condition when the complex dimension of the underlying manifold is at least 2. In this article it will be shown that, in a certain well-defined sense, the space of Bochner-Kähler metrics in complex dimension n has real dimension n+1 and a recipe for an explicit formula for any Bochner-Kähler met...

We investigate the geometry and topology of submanifolds under a sharp pinching condition involving extrinsic invariants like mean curvature length second fundamental form. Homology vanishing results are given that strengthen sharpen previous ones. In addition, an integral bound is provided for Bochner operator compact Euclidean in terms Betti numbers.
