Given a simple, connected graph, a pebbling configuration (or just configuration) is a function from its vertex set to the nonnegative integers. A pebbling move between adjacent vertices removes two pebbles from one vertex and adds one pebble to the

Let G be a connected graph. A configuration of pebbles assigns a nonnegative integer number of pebbles to each vertex of G . A move consists of removing two pebbles from one vertex and placing one pebble on an adjacent vertex. A configuration is solv

Let G be a connected graph. A configuration of pebbles on G is a function that assigns a nonnegative integer to each vertex. A pebbling move consists of removing two pebbles from one vertex and placing one pebble on an adjacent vertex. A configuratio

Consider a connected graph and a configuration of pebbles on its vertices. A pebbling step consists of removing two pebbles from a vertex and placing one on an adjacent vertex. A configuration is called solvable if it is possible to place a pebble on

53 Music theorists face many challenges when analyzing music written according to George Perle’s compositional theory of twelve-tone tonality, a system based on inversional symmetry. Analysts focusing on Mr. Perle’s music seek relationships among

We develop the notion of t-homogeneous, G-semiregular large sets of t-designs, show that there are infinitely many 3-homogeneous PSL(2, q)-semiregular large sets when q\equiv 3 \mod 4, two sporadic 3-homogeneous A \GammaL(1,32)-semiregular large sets

We determine the distribution of 3−(q + 1,k,λ) designs, with k ϵ {4,5}, among the orbits of k-element subsets under the action of PSL(2,q), for q ϵ 3 (mod 4), on the projective line. As a consequence, we give necessary and sufficient conditions

Online casual games can be used to significantly enhance the productivity of volunteer computing. We call games which perform volunteer computing volunteer computing games. We introduce Wildfire Wally, a volunteer computing game capable of solving th
