Abstract: Let ℌ be a complex Hilbert space with dimℌ ≥ 3 and $${\cal B}({\cal H})$$ℬ(ℋ) the algebra of all bounded linear operators on ℌ. Let ≤◇ be the diamond order on $${\cal B}({\cal H})$$ℬ(ℋ), that… read more here.

Abstract: In this paper, the pricing competition models have been studied between two substitutable and one complementary products in a two-echelon fuzzy supply chain system. Here, three manufacturers separately (one each) produce and sell their products… read more here.

Abstract: In this paper, we present new kind analogues of the Filbert and Lilbert matrices via products of two k-tuples asymmetric entries consist of the Fibonacci and Lucas numbers. We shall derive explicit formulas for their… read more here.
