An enterprise-wide database built via Oracle*CASE is a hot topic. We describe the PEP-II~ABAR ProjectWide Database [1], and the lessons learned in delivering and developing this system with a small team averaging two and one half people. We dso give some details of providing World Wide Web (WW~ access to the information, and using .Oracle*CASE and Oracle Forrns4. The B Factory at the Stanford L...

We give a simple method to calculate the semiclassical D-brane boundary states of the bosonic string propagating in an arbitrary curved spacetime in a perturbative approach in which the metric gAB and the constant antisymmetric Kalb-Ramond field bAB form the general background which is treated exactly. As an important particular case, it is shown that at the first order perturbation theory ther...

In any semigroup S, we say that elements a and b are left inverses of each other if a = aba, b = bab and a L b, in which case we write a γ b. Right inverses are defined dually with the notation δ. Set τ = δγ. We study the classes of semigroups in which τ has some of the usual properties of a relation. We also consider properties of (maximal) completely simple subsemigroups of S. In terms of the...

We study the geodesic growth series of the braid group on three strands, B3 := 〈a, b|aba = bab〉. We show that the set of geodesics of B3 with respect to the generating set S := {a, b} ±1 is a regular language, and we provide an explicit computation of the geodesic growth series with respect to this set of generators. In the process, we give a necessary and sufficient condition for a freely redu...

In memory of Daniel Mollier, our former mathematics teacher at the Lycée Louis le Grand, Paris. Consider the braid group B3 = 〈a, b|aba = bab〉 and the nearest neighbor random walk defined by a probability ν with support {a, a−1, b, b−1}. The rate of escape of the walk is explicitly expressed in function of the unique solution of a set of eight polynomial equations of degree three over eight ind...
