Homotopy Groups of K-contact Toric Manifolds
We compute the first and second homotopy groups of a class of contact toric manifolds in terms of the images of the associated moment map.
متن کاملTORIC MORPHISMS BETWEEN p-COMPACT GROUPS
It is well-known that any morphism between two p-compact groups will lift, nonuniquely, to an admissible morphism between the maximal tori. We identify here a class of pcompact group morphisms, the p-toric morphisms, which can be perceived as generalized rational isomorphisms, enjoying the stronger property of lifting uniquely to a morphism between the maximal torus normalizers. We investigate ...
متن کاملOn the Grothendieck groups of toric stacks
In this note, we prove that the Grothendieck group of a smooth complete toric Deligne-Mumford stack is torsion free. This statement holds when the generic point is stacky. We also construct an example of open toric stack with torsion in K-theory. This is a part of the author’s Ph.D thesis. A similar result has been proved by Goldin, Harada, Holm, Kimura and Knutson in [GHHKK] using symplectic m...
متن کاملOn the Selection of Pairing-Friendly Groups
We propose a simple algorithm to select group generators suitable for pairing-based cryptosystems. The selected parameters are shown to favor implementations of the Tate pairing that are at once conceptually simple and efficient, with an observed performance about 2 to 10 times better than previously reported implementations, depending on the embedding degree. Our algorithm has beneficial side ...
متن کاملExponentiation in Pairing-Friendly Groups Using Homomorphisms
We present efficiently computable homomorphisms of the groups G2 and GT for pairings G1 × G2 → GT . This allows exponentiation in G2 and GT to be accelerated using the Gallant-Lambert-Vanstone method.
