Examples
Geometry Search for the term Geometry in any field. Queries are case-independent.
Funct* Wildcard queries are specified by * (e.g. functions, functorial, etc.). Otherwise the search is exact.
"Topological group" Phrases (multi-words) should be set in "straight quotation marks".
au: Bourbaki & ti: Algebra Search for author and title. The and-operator & is default and can be omitted.
Chebyshev | Tschebyscheff The or-operator | allows to search for Chebyshev or Tschebyscheff.
"Quasi* map*" py: 1989 The resulting documents have publication year 1989.
so: Eur* J* Mat* Soc* cc: 14 Search for publications in a particular source with a Mathematics Subject Classification code (cc) in 14.
"Partial diff* eq*" ! elliptic The not-operator ! eliminates all results containing the word elliptic.
dt: b & au: Hilbert The document type is set to books; alternatively: j for journal articles, a for book articles.

Contact CR-warped product submanifolds in generalized Sasakian space forms. (English) Zbl 1109.53056
Summary: In [Monatsh. Math. 133, 177–195 (2001; Zbl 0996.53044)] B. Y. Chen studied warped product CR-submanifolds in Kähler manifolds. Afterwards, I. Hasegawa and I. Mihai [Geom. Dedicata 102, 143–150 (2003; Zbl 1066.53103)] obtained a sharp inequality for the squared norm of the second fundamental form for contact CR-warped products in Sasakian space forms. Recently, P. Alegre, D. E. Blair and A. Carriazo [Isr. J. Math. 141, 157–183 (2004; Zbl 1064.53026)] introduced generalized Sasakian space forms. The aim of the present paper is to study contact CR-warped product submanifolds in a generalized Sasakian space form.
