Krasner $F^{(m, n)}$-Hyperrings

$!!!!$ In this paper, the notion of fuzzy $!$ Krasner $!(m, n)$-hyperrings($!F^{(m, n)}!$-hyperrings) by using the notion of$F^m$-hyperoperations and $F^n$-operations is introduced and somerelated properties are investigated. In this regards,relationships between Krasner $F^{(m, n)}$-hyperrings and Krasner$(m, n)$-hyperrings are considered. We shall prove that everyKrasner $F^{(m, n)}$-hyperrin...

Thompson ’ s group F ( n ) is not minimally almost convex

We prove that Thompson’s group F (n) is not minimally almost convex with respect to the standard finite generating set. A group G with Cayley graph Γ is not minimally almost convex if for arbitrarily large values of m there exist elements g, h ∈ Bm such that dΓ(g, h) = 2 and dBm (g, h) = 2m. (Here Bm is the ball of radius m centered at the identity.) We use tree-pair diagrams to represent eleme...

Cultured cells cloned from the C1300 neuroblastoma have been shown by several laboratories to extend neurites (1-6) and to accumulate nervespecific enzymatic activities (7) when grown under conditions in which cell division is inhibited. Study of this system has been stimulated by the hope that it might serve as an in vitro model of nerve cell differentiation. Many of the neurite-inducing agent...

• BioGeoChemie des Watts Auf Beschluss der Deutschen Forschungsgemeinschaft wird an der Universität Oldenburg für die Dauer von sechs Jahren eine Forschergruppe "BioGeoChemie des Watts" eingerichtet. In den ersten drei Jahren erhält die Gruppe fast sechs Millionen DM Förderung. Der Antrag wurde federführend vom Institut für Chemie und Biologie des Meeres (ICBM) vorbereitet. Beteiligt sind außer...
