Computing Chevalley Bases in Small Characteristics
Let L be the Lie algebra of a simple algebraic group defined over a field F and let H be a split maximal toral subalgebra of L. Then L has a Chevalley basis with respect to H. If char(F) 6= 2, 3, it is known how to find it. In this paper, we treat the remaining two characteristics. To this end, we present a few new methods, implemented in Magma, which vary from the computation of centralisers o...
متن کاملSmall degree representations of finite Chevalley groups in defining characteristic
We determine for all simple simply connected reductive linear algebraic groups defined over a finite field all irreducible representations in their defining characteristic of degree below some bound. These also give the small degree projective representations in defining characteristic for the corresponding finite simple groups. For large rank l our bound is proportional to l3 and for rank 11 m...
متن کاملComputing inhomogeneous Gröbner bases
In this paper we describe how an idea centered on the concept of self-saturation allows several improvements in the computation of Gröbner bases via Buchberger’s Algorithm. In a nutshell, the idea is to extend the advantages of computing with homogeneous polynomials or vectors to the general case. When the input data are not homogeneous, we use a technique described in Section 2: the main tool ...
متن کاملComputing minimal interpolation bases
We consider the problem of computing univariate polynomial matrices over a field that represent minimal solution bases for a general interpolation problem, some forms of which are the vector M-Padé approximation problem in [Van Barel and Bultheel, Numerical Algorithms 3, 1992] and the rational interpolation problem in [Beckermann and Labahn, SIAM J. Matrix Anal. Appl. 22, 2000]. Particular inst...
متن کاملSmall Finger Metacarpal Shaft Wedged between Ring and Small Metacarpal Bases: a Report of 2 Cases
We present two patients with a displaced fracture of the small finger metacarpal base, where the shaft of the small finger metacarpal was wedged between the bases of the ring and small finger metacarpals. The striking appearance on radiographs led to initial recommendations for surgery, but both patients preferred non-operative treatment and did well in the short term without surgery
