TORI (SINGULAR torus) are among the most common benign jaw lesions. The magnetic resonance imaging (MRI) characteristics have not been reported yet. We present a 72-year-old patient with mandibular tori, which were detected as an incidental finding on MRI and provide an overview of the imaging features of tori.

We describe the isomorphism class of the torus centralizing a regular, semi-simple, stable conjugacy class in a simply-connected, semi-simple group. Let k be a field, and let G be a semi-simple, simply-connected algebraic group, which is quasi-split over k. The theory of semi-simple conjugacy classes in G is well understood, from work of Steinberg [S] and Kottwitz [K]. Any semi-simple conjugacy...

We consider Narain T-duality on a nontrivially fibered n-torus bundle in the presence of a topologically nontrivial NS H flux. The action of the duality group on the topology and H flux of the corresponding type II and heterotic string backgrounds is determined. The topology change is specialized to the case of supersymmetric T-fibered torsional string backgrounds with nontrivial H flux. We pro...

Let G be a simple Lie group with a maximal torus T . We construct the cohomology ring H∗(G; Z) in terms of Schubert classes on G/T . 2000 Mathematical Subject Classification: 55T10; 14M15

We use the Bateman-Horn conjecture to study the order of the set of Fq-rational points of primitive subgroups that arise in torus-based cryptography. We provide computational evidence to support the heuristics and make some suggestions regarding parameter selection for torus-based cryptography.

the broadcast domination number of the cartesian product of two cycles is completely determined.

Elliptic genera of level N have been defined by F. Hirzebruch, generalising the earlier notion of elliptic genus due to S. Ochanine. We show that there are corresponding elliptic cohomology theories which are naturally associated to such genera and that these are obtained from the level 1 case by algebraic extension of the coefficient rings from level 1 to level N modular forms. Introduction. I...
