Algebraic Groups I. Unipotent radicals and reductivity
In class, we have proved the important fact that over any field k, a non-solvable connected reductive group containing a 1-dimensional split maximal k-torus is k-isomorphic to SL2 or PGL2. That proof relied on knowing that maximal tori remain maximal after a ground field extension to k, and so relies on Grothendieck’s theorem. But for algebraically closed fields there is no content to Grothendi...
متن کاملCharacterising Strongly Normalising Intuitionistic Terms
This paper gives a characterisation, via intersection types, of the strongly normalising proof-terms of an intuitionistic sequent calculus (where LJ easily embeds). The soundness of the typing system is reduced to that of a well known typing system with intersection types for the ordinary λ-calculus. The completeness of the typing system is obtained from subject expansion at root position. Next...
متن کاملOn Normalising Radial Basis Function
Normalisation of the basis function activations in a radial basis function (RBF) network is a common way of achieving the partition of unity often desired for modelling applications. It results in the basis functions covering the whole of the input space to the same degree. However, normalisa-tion of the basis functions can lead to other eeects which are sometimes less desireable for modelling ...
متن کاملNormalising the crisis in Africa.
Developmental relief has become the central doctrine of 'good practice' in humanitarian responses to complex political emergencies. This is despite the fact that a proliferation of such emergencies reflects a failure of development for people in those countries in crisis. Drawing on case study material from Sudan, Somalia, Rwanda and Uganda, this paper challenges assumptions made about the effi...
متن کاملConventional pituitary irradiation is effective in normalising plasma IGF-I in patients with acromegaly.
OBJECTIVE For patients in whom acromegaly persists despite pituitary surgery, conventional pituitary irradiation represents an additional treatment option. A 30-60% cure rate is described in the literature, but these studies did not utilise strict rules of remission, such as "safe" GH levels <2.5 microg/l, and age-adjusted normal IGF-I levels. DESIGN AND METHODS We report the outcome of 41 pa...
