On Rubin's variant of the p-adic Birch and Swinnerton-Dyer conjecture II
Let E be an elliptic curve over Q with complex multiplication by the ring of
integers of an imaginary quadratic field K. In 1991, by studying a certain
special value of the Katz two-variable p-adic L-function lying outside the
range of -adic interpolation, K. Rubin formulated a p-adic variant of the
Birch and Swinnerton-Dyer conjecture when is infinite, and he proved
that his conjecture is true for E(K) of rank one.
When E(K) is finite, however, the statement of Rubin's original conjecture no
longer applies, and the relevant special value of the appropriate -adic
L-function is equal to zero. In this paper we extend our earlier work and give
an unconditional proof of an analogue of Rubin's conjecture when E(K) is
finite.Comment: Final version. To appear in Mathematische Annalen
The Hulthen Potential in D-dimensions
An approximate solution of the Schrodinger equation with the
Hulthn potential is obtained in D-dimensions with an exponential
approximation of the centrifugal term. Solution to the corresponding
hyper-radial equation is given using the conventional Nikiforov-Uvarov method.
The normalization constants for the Hulthn potential are also
computed. The expectation values , are also obtained using
the Feynman-Hellmann theorem.Comment: Typed with LateX, 12 Pages, typos correcte
Impact of organizational culture on the performances of universities in Nigeria
This study examines the impact of organizational culture on performances of Universities in Ogun State, Nigeria. The objectives of the study were to identify which element of organizational culture has the most contribution in predicting the performances of Universities, and to reveal the relationship that exists between organizational culture and performances of Universities. To determine the impact of organizational culture on performances of Universities, a sample of 300 academic and non-academic staff of Covenant University, Ota, Olabisi Onabanjo University, Ago-Iwoye, University of Agriculture, Abeokuta, all in Ogun State were drawn. The data were analyzed using simple frequency tables, Pearson product moment correlation and multiple regressions. The finding shows that there is no significant contribution of organizational culture in predicting the performances of Universities and some elements of organizational culture contributed predicting the performances of Universities in Ogun State. Finally, the analysis shows that there is no significant relationship between organizational culture and performances of the Universities studied. The general agreement is that positive organizational culture will have a positive impact on performance of any University
On twisted forms and relative algebraic K-theory
This paper introduces a new approach to the study of certain aspects of
Galois module theory by combining ideas arising from the study of the Galois
structure of torsors of finite group schemes with techniques coming from
relative algebraic -theory.Comment: Final version. To appear in the Proceedings of the London
