Description:
Neil J. A. Sloane, Rutgers Experimental Mathematics Seminar, October 10, 2013.nnSee part 1 at https://vimeo.com/76725343.nnAbstract: For integers g >= 2, k >= 2, call a number N a (g,k)-reverse multiple if the reversal of N in base g is equal to k times N. The numbers 1089 and 2178 are the two smallest (10,k)-reverse multiples, their reversals being 9801 = 9x1089 and 8712 = 4x2178. In 1992, A. L. Young introduced certain trees in order to study the problem of finding all (g,k)-reverse multiples.

More generally, V(r) may be replaced by the standardized Riesz pair-energy. In a recent paper with Brauchart and Nerattini we inquired into the concavity of the map from the")

Despite their wide ranging applications, very little is known about the set of Garcia numbers. In this talk we talk about some recent work on the structure of")
