Putting t = 1 in Definition 7 we get A Fixed Point Theorem for Nonexpansive Mappings in Locally ... min) satisfy the following condition: For each fixed t ∈ R, the function F x (t):X → [0, 1] is weakly lower semi- continuous in x ∈ X.

... W ,∞ (R n ). The following result is an extension of the Gagliardo-Nirenberg inequality ([2 - 6]) to Lorentz spaces. Note that the Gagliardo-Nirenberg inequality has applications to partial differential ... of the Gagliardo-Nirenberg inequality to Lorentz spaces. Let Φ : [0, ∞) → [0, ∞) be a non-zero concave function, which is non-decreasing and Φ(0+) = Φ(0) = 0. We put Φ(∞) =...

... well as an analog of Schur-Weyl duality for R n , and Halverson et al.[1] have found an R n analog of the Murnaghan-Nakayama rule, a combinatorial construction of the irreducible characters of ... In this paper, we analyze the representations of a related algebraic structure called the rook monoid from a combinatorial angle. In particular, we give a combinatorial const...
