Bahram Peimani-Fard was born in 1941, in Yazd, Iran, where he completed his elementary, and high school education. He received his M.Sc. degree in Soil and Water Engineering from the Faculty of Agriculture, Shiraz University. Then, he was employed in the Range Improvement and Forage Supply Organization, affiliated with the Ministry of Agriculture to collaborate with Mr. Kernik, the FAO expert...

A cross-intersecting Erdős-Ko-Rado set of generators of a finite classical polar space is a pair (Y,Z) of sets of generators such that all y ∈ Y and z ∈ Z intersect in at least a point. We provide upper bounds on |Y | · |Z| and classify the crossintersecting Erdős-Ko-Rado sets of maximum size with respect to |Y | · |Z| for all polar spaces except some Hermitian polar spaces.

Ahlswede and Khachatrian's diametric theorem is a weighted version of their complete intersection theorem, which is itself a well known extension of the t-intersecting Erd˝ os-Ko-Rado theorem. The complete intersection theorem says that the maximum size of a family of subsets of [n] = {1,. .. , n}, every pair of which intersects in at least t elements, is the size of certain trivially intersect...

Let S(n) be the symmetric group on n points. A subset S of S(n) is intersecting if for any pair of permutations π, σ in S there is a point i ∈ {1, . . . , n} such that π(i) = σ(i). Deza and Frankl [9] proved that if S ⊆ S(n) is intersecting then |S| ≤ (n− 1)!. Further, Cameron and Ku [4] show that the only sets that meet this bound are the cosets of a stabilizer of a point. In this paper we giv...

1. Two vector bundles E and F over the finite connected CW complex X are /-equivalent, if their sphere-bundles S(E) and S(F) are of the same fiber-homotopy type. If they become /-equivalent after a suitable number of trivial bundles is added to both of them they are stably /-equivalent. This note concerns itself with a new stable /-invariant 6(E), which was suggested by the recent work of Atiya...

In this study, the current issues of athlete brand management are discussed and the construct of athlete brand image is conceptualized. A conceptual model of athlete brand image (MABI) is developed incorporating three key dimensions: athletic performance, attractive appearance, and marketable lifestyle. These dimensions are defined by an athlete’s on-field characteristics, attractive external a...
