Afshin 2 Let V and W be two real vector spaces and let ;sim be a relation on both V and W. A linear function T : V → W is said to be a linear preserver (respectively strong linear preserver) of ;sim if Tx ;sim Ty whenever x ;sim y (respectively Tx ;sim Ty if and only if x ;sim y). In this paper we characterize all linear functions T : M_{n,m} → M_{n,k} which preserve or strongly preserve multivariate and directional majorization. http://ijmsi.ir/article-1-105-en.pdf Doubly Stochastic matrices Directional majorization Multivariate majorization Linear preserver. eng ACECR at Tarbiat Modares University Iranian Journal of Mathematical Sciences and Informatics 1735-4463 2008-9473 2010-05 5 1 7 18 article A. Askari Hemmat 1 Z. Rahbani 2 In this paper using the Clifford algebra over R4 and its matrix representation, we construct Clifford scaling functions and Clifford wavelets. Then we compute related mask functions and filters, which arise in many applications such as quantum mechanics. http://ijmsi.ir/article-1-106-en.pdf Clifford Wavelets Clifford algebra Multiresolution Analysis Wavelets. eng ACECR at Tarbiat Modares University Iranian Journal of Mathematical Sciences and Informatics 1735-4463 2008-9473 2010-05 5 1 19 26 article Reza Jahani-Nezhad 1 Let R be a commutative integral domain with quotient field K and let P be a nonzero strongly prime ideal of R. We give several characterizations of such ideals. It is shown that (P : P) is a valuation domain with the unique maximal ideal P. We also study when P^{;minus1} is a ring. In fact, it is proved that P^{;minus1} = (P : P) if and only if P is not invertible. Furthermore, if P is invertible, then R = (P : P) and P is a principal ideal of R. http://ijmsi.ir/article-1-107-en.pdf Strongly prime ideal Divided ideal Valuation domain. eng ACECR at Tarbiat Modares University Iranian Journal of Mathematical Sciences and Informatics 1735-4463 2008-9473 2010-05 5 1 27 39 article A.
