p-adic Strings and their Applications

The theory of p-adic strings is reviewed along with some of their applications, foremost among them to the tachyon condensation problem in string theory. Some open problems are discussed, in particular that of the superstring in 10 dimensions as the end-stage of the 26-dimensional closed bosonic string's tachyon condensation.Comment: 12 pages, Based on a talk at the 2nd International Conference on p-adic Mathematical Physics, 15 - 21 September 2005, Belgrade, Serbia and Montenegr
