We consider a class of nonlinear Schrodinger equations in N = 3, 4, 5 space dimensions with an attractive potential. The nonlinearity is local but rather general encompassing for the first time both subcritical and ...

Two fundamental properties of the ordinary doubly infinite tape of a Turing machine are hidden behind the contents of the symbols written on it. An observer standing on a blank tape will be unable to distinguish one cell ...

In algebraic graph theory one studies algebraic variants of graphs by forming matrices and groups relating to the graph. One example of this is the distance matrices, $\Gamma\sb{\rm i}$, and their associated groups.

Much of the work in algebraic K-theory today is devoted to the search for "motivic cohomology." This hoped-for cohomology theory of algebraic geometry should be analogous to the known singular homology groups of topology. ...

Dynamical properties of the baker's transformation B with integer base $b\ge 2$ and several related maps on discrete subsets of the domain are studied. The baker's transformation with base $b,\ B: \lbrack 0,1)\times\lbrack ... application/pdf PDF (4MB) • (1972) application/pdf PDF (2MB) • (1998) The definition of the Baum-Connes map is extended to the case of any smooth groupoid. Then we prove that the Baum-Connes map is invariant under the groupoid equivalence. application/pdf PDF (4MB) • (2012-09-18) This dissertation is divided into three main sections. The main result of Section 1 is that, for$a,b>1$, irrational, the quantity$\log (a/b)$is not too far'' from the series of fractional parts$\$ \sum_{n=1}^{\i ...

This thesis is a study of the axiomatics of quantum vertex algebras based on the bicharacter construction suggested by R. Borcherds in [Bor01]. One of the goals is to use the ideas of [Bor01] to incorporate the examples ...

This thesis considers the notions of decomposable operators in the sense of C. Foias, and a certain analytic condition--called condition ((beta))--due to Errett Bishop. It is shown that the concepts are related, and that ...
