Elements in Small Characteristic
Let k be an algebraically closed field of characteristic exponent p ≥ 1. Let G be a connected reductive algebraic group over k and let g be the Lie algebra of G. Note that G acts on G and on g by the adjoint action. Let UG be the variety of unipotent elements of G. Let Ng be the variety of nilpotent elements of g. In [L2], we have proposed a definition of a partition of UG into smooth locally c...

of the Paper Information Technology (IT) has got tremendous potential for enhancing the operational efficiency of banks and strengthening their risk management capability, particularly credit risk management. Taking the case of Old Private sector Banks (OPBs) in Kerala state, this paper seeks to analyse the role of IT in improving their net interest margin (NIM) and non-interest margin (NOM), t...
متن کاملGreen Computing
Green computing refers to the practice and procedures of using computing resources in an environment friendly way while maintaining overall computing performance. Global warming is the continuing rise in the average temperature of the Earth’s climate system due to a range of factors. Scientific understanding of the various causes of global warming has been increasing since the last decade. Clim...
متن کاملExponential Functions in Prime Characteristic
In this note we determine all power series F (X) ∈ 1 + XFp[[X ]] such that (F (X + Y )) F (X)F (Y ) has only terms of total degree a multiple of p. Up to a scalar factor, they are all the series of the form F (X) = Ep(cX) ·G(X ) for some c ∈ Fp and G(X) ∈ 1 + XFp[[X ]], where Ep(X) = exp ( ∑
متن کاملUnipotent Elements in Small Characteristic
0.1. Let k be an algebraically closed field of characteristic exponent p ≥ 1. Let G be a reductive connected algebraic group over k. Let U be the variety of unipotent elements of G. The unipotent classes of G are the orbits of the conjugation action of G on U . The theory of Dynkin and Kostant [Ko] provides a classification of unipotent classes of G assuming that p = 1. It is known that this cl...
