LIMIT LAWS FOR SYMMETRIC k-TENSORS OF REGULARLY VARYING MEASURES
In this paper we establish the asymptotics of certain symmetric k–tensors whose underlying distribution is regularly varying. Regular variation is an asymptotic property of probability measures with heavy tails. Regular variation describes the power law behavior of the tails. Tensors and tensor products are useful in probability and statistics, see for example [7, 14, 17]. Random tensors are co...
متن کاملKilling-yano Tensors and Nambu Tensors
We present the conditions when a Killing-Yano tensor becomes a Nambu tensor. We have shown that in the flat space case all Killing-Yano tensors are Nambu tensors. In the case of Taub-NUT metric and Kerr-Newmann metric we found that a Killing-Yano tensor of order two generate a Nambu tensor of order three. after 1st September 1999 at Institute of Space Sciences,Bucharest-Magurele, Romania e-mail...
متن کاملLax Tensors, Killing Tensors and Geometric Duality
The solution of the Lax tensor equations in the case Lαβγ = −Lβαγ was analyzed. The Lax tensors on the dual metrics were investigated. We classified all two dimensional metrics having the symmetric Lax tensor Lαβγ . The Lax tensors of the flat space, Rindler system and its dual were found.

متن کاملKilling Tensors and Conformal Killing Tensors from Conformal Killing Vectors
Koutras has proposed some methods to construct reducible proper conformal Killing tensors and Killing tensors (which are, in general, irreducible) when a pair of orthogonal conformal Killing vectors exist in a given space. We give the completely general result demonstrating that this severe restriction of orthogonality is unnecessary. In addition we correct and extend some results concerning Ki...
