Weakly-split spherical Tits systems in pseudo-reductive groups By Gopal Prasad Dedicated to C. S. Seshadri on his 80th birthday

چکیده
We will prove that any weakly-split spherical Tits system (B,N) inG = G(k) (G a reductive or a pseudo-reductive k-group) satisfying some natural conditions is “standard”. In particular, if G is anisotropic over k, then such a Tits system is trivial, i.e., B = G.

A NEW APPROACH TO UNRAMIFIED DESCENT IN BRUHAT-TITS THEORY By Gopal Prasad Dedicated to my wife
We give a new approach to unramified descent in Bruhat-Tits theory of reductive groups over a discretely valued field k, with Henselian local ring and perfect residue field, which appears to be conceptually simpler, and more geometric, than the original approach of Bruhat and Tits. We are able to derive the main results of the theory over k from the theory over the maximal unramified extension ...

متن کاملOn Mordell-weil Groups of Elliptic Curves Induced by Diophantine Triples
We study the possible structure of the groups of rational points on elliptic curves of the form y2 = (ax + 1)(bx + 1)(cx + 1), where a, b, c are non-zero rationals such that the product of any two of them is one less than a square. Dedicated to Professor Sibe Marde2i¢ on the occasion of his 80th birthday.
متن کاملCoincidence Rotations of the Root Lattice a 4 Dedicated to Ludwig Danzer on the Occasion of His 80th Birthday
The coincidence site lattices of the root lattice A4 are considered, and the statistics of the corresponding coincidence rotations according to their indices is expressed in terms of a Dirichlet series generating function. This is possible via an embedding of A4 into the icosian ring with its rich arithmetic structure, which recently [6] led to the classification of the similar sublattices of A...
