Yarı Devirli Ricci Simetrik Manifoldlar Üzerine

Year 2011, Volume: 6 Issue: 1, 73 - 81, 16.05.2011

Abstract

Özet: Bu makalenin amacı, konsirkular simetrik (PCRS)n, konsirkular tekrarlı (PCRS)n, ayrışabilir (PCRS)n manifoldları incelemektir. (PCRS)n ayrışabilir manifoldunda ayrışımlardan birisinin Ricci düzlemsellik (flat), diğerinin de devirli paralellik olduğu gösterilmiştir. Aynı zamanda (PCRS)n nin tümüyle umbilik hiperyüzeyleri çalışılmıştır.

Abstract

Abstract: The object of the present paper is to study concircularly
symmetric (PCRS)n, concircularly recurrent (PCRS)n, decomposable
(PCRS)n. Among others it is shown that in a decomposable (PCRS)n one of
the decompositions is Ricci flat and the other decomposition is cyclic
parallel. The totally umbilical hypersurfaces of (PCRS)n are also
studied.
