Noncommutative Tachyons And String Field Theory
E. Witten
It has been shown recently that by turning on a large noncommutativity parameter, the description of tachyon condensation in string theory can be drastically simplified. We reconsi…

A Derivation of K-Theory from M-Theory
Diuliu-Emanuel Diaconescu, Gregory Moore, Edward Witten
We show how some aspects of the K-theory classification of RR fluxes follow from a careful analysis of the phase of the M-theory action. This is a shortened and simplified companio…

The Cosmological Constant From The Viewpoint Of String Theory
Edward Witten
The mystery of the cosmological constant is probably the most pressing obstacle to significantly improving the models of elementary particle physics derived from string theory. The…
