The pebbling threshold spectrum and paths

Autor: Moews, David

Given a distribution of pebbles on the vertices of a graph, say that we can pebble a vertex if a pebble is left on it after some sequence of moves, each of which takes two pebbles from some vertex and places one on an adjacent vertex. A distribution

The motif problem

Autor: Canfield, E. Rodney, Fertig, Ron, Mauldin, R. Daniel, Moews, David

Fix a choice and ordering of four pairwise non-adjacent vertices of a parallelepiped, and call a motif a sequence of four points in R^3 that coincide with these vertices for some, possibly degenerate, parallelepiped whose edges are parallel to the ax

The probability that a random monic p-adic polynomial splits into linear factors

Autor: Buhler, Joe, Goldstein, Daniel, Moews, David, Rosenberg, Joel

Let n be a positive integer and let p be a prime. We calculate the probability that a random monic polynomial of degree n with coefficients in the ring Z_p of p-adic integers splits over Z_p into linear factors.

The identity is the most likely exchange shuffle for large n

Autor: Goldstein, Daniel, Moews, David

Publikováno v: Aequationes Mathematicae, 65, #1-2 (February 2003), pp 3-30

Let a deck of n cards be shuffled by successively exchanging the cards in positions 1, 2, ..., n with cards in randomly chosen positions. We show that for n equal to 18 or greater, the identity permutation is the most likely. We prove a surprising sy
