The geometry of anti-invariant submanifolds of a complex space form with positive definite metric was studied by Chen-Ogiue [2], Yano-Kon [6] and others. In this paper we study the geometry of indefinite anti-invariant ...

Uganda is a landlocked country in East Africa. It is bordered on the east by Kenya, north by Sudan, west by the Democratic Republic of Congo, southwest by Rwanda and to the south by Tanzania. It has an area of 236,040 ...

The purpose of this paper is to study the geometry of an n-dimensional anti-invariant maximal spacelike submanifold M immersed in a 2(n+p)-dimensional indefinite complex space form Mc c ( ), 0 ≠ of holomorphic sectional ...

Y. B. Shen [5] studied curvature pinching for 3-dimensional minimal submanifold in a sphere. In addition, Shen showed that if the scalar curvature of M3 is larger than 4, then M3 is totally geodesic. The purpose of this ...

In various papers some authors have previously investigated [1], [2], [3], [4], [5] and determined the spectrum of weighted mean matrices considered as bounded operators on various sequence spaces. In this study, we determine ...

In summability theory, different classes of matrices have been investigated and characterized. There are various types of summability methods e.g. Nörlund means, Cesaro, Riesz, Euler, Abel and many others. The spectrum ...

This paper, analyses the properties of international standard serial number in terms of error detection, correction and the size of the code dictionary. Through weight check equation the ability of ISSN code to detect and ...
