A remark concerning graphical sequences

In “A note on a theorem of Erdös & Gallai” ([6]) one identifies the nonredundant inequalities in a characterization of graphical sequences. We explain how this result may be obtained directly from a simple geometrical observation involving weak majorization. A sequence of positive integers d1, d2, . . . , dp is called graphical if it is the degree sequence of a graph, i.e., there is a graph who...

A Remark on Parity Sequences

If n = 2, then the set j£ is closely related to the Fibonacci sequence; specifically, t GT2 iff the 7 term of the Fibonacci sequence is odd. We ask, for each w, which numbers are uniquely expressible as the sum of two distinct elements of Tn. In general, for any given w, one can determine exactly which numbers are uniquely expressible. If w = 2, it is easy to see that there are five such number...

A Sum concerning Sequences

Let A={a(n)} co n=1 be a sequence of positive integers. In this paper we prove that if the trailing digit of a(n) is not zero for any n, then sum of a(n)/Rev Ca(n)) is divergent

A remark concerning random walks with random potentials

We consider random walks where each path is equipped with a random weight which is stationary and independent in space and time. We show that under some assumptions the arising probability distributions are in a sense uniformly absolutely continuous with respect to the usual probability distribution for symmetric random walks. We consider random walks on the d-dimensional lattice Z with each pa...
