Discrete Time Bisexual Branching Processes in Varying Environments
Get PDF2000 Mathematics Subject Classification: 60J80This paper concerns with the bisexual branching process in varying environments introduced in [16]. For such a model a survey of results is provided. Previously, brief descriptions about the bisexual branching process and some bisexual models derived from it are given.Research supported by the Plan Nacional de Investigaci on Cientifi ca, Desarrollo e Innovacion Tecnologica, grant BFM2003-06074
Generalized (Îș, ”)-space forms and d-homothetic deformations
Get PDFWe study the Da-homothetic deformations of generalized (Îș, ”)-
space forms. We prove that the deformed spaces are again generalized
(Îș, ”)-space forms in dimension 3, but not in general, although a slight
change in their definition would make them so. We give infinitely many
examples of generalized (Îș, ”)-space forms of dimension 3
