... nonempty and closed subset of the Banach space X. The E-L measure of nonconvexity µ of X is said to have the Cantor property in Y if for every decreasing sequence {A n } ∞ n=1 of nonempty, closed, and ... terms of the Cantor property for the E-L measure of nonconvexity. As an application of this characterization, we show that the convexity requirements can be d...

... understanding of the ln(s) operator, the Laplace-domain logarithmi c operator, and determine what special properties are asso- ciated with it. The motivation is the frequent occurrence of the ln(s) ... demonstrates that the ln(s) operator appears frequently. The next section will review the necessary results from fractional calculus and the theory of order-distribu...

... Let C ρ denote the subset of C with peg permutation ρ. This is not a permutation class (the peg permutation of σ ≤ π need not be the peg permutation of π), but the set of non- peg vectors of permutations ... allows us to give a new, short proof of the Fibonacci dichotomy: the number of permutations of length n in a permutation class is either at least as...
