... development of string theory as a unified de- scription of elementary particles, including their gravitational interactions. Although still very incomplete, string theory appears to be a far more con- sistent ... enormous. Thus, it is difficult to understand how there can be an ambiguity. The real proton propagating through space-time is not the simple struc- tureless bare proton. The in...

... Yang-Mills theory on a noncommutative torus has been proposed as an example [3]. Though this example at first sight appears to be neither covariant nor causal, it has proved to arise in string theory ... noncommutative Yang-Mills theory with string winding states and other stringy ex- citations. This makes the framework of noncommutative Yang-Mills theory seem very powerful. Su...

All string ... a mysterious feature shows up. The lowest mass state, referred to as |0, has 1 2 M 2 = −a, and appears to be non-degenerate: there is just one such state. Let us now count all first-...
