“…This induces a specific local coordinate system at the external punctures on the Riemann surfaces represented by F∆ F (see e.g. [42,43]). By the compatibiity condition discussed in point 6, this is the correct choice of coordinate system on the Riemann surfaces in the original system.…”

String theory gives a well defined procedure for computing the S-matrix of BPS or a class of massless states, but similar calculation for general massive states is plagued with difficulties due to mass renormalization effect. In this paper we describe a procedure for computing the renormalized masses and S-matrix elements in bosonic string theory for a special class of massive states which do not mix with unphysical states under renormalization. Even though this requires working with off-shell amplitudes which are ambiguous, we show that the renormalized masses and S-matrix elements are free from these ambiguities. We also argue that the masses and S-matrix elements for general external states can be found by examining the locations of the poles and the residues of the S-matrix of special states. Finally we discuss generalizations to heterotic and superstring theories.

“…Поэтому нам нужно только два условия, чтобы одно-значно фиксировать виттеновскую башню. Наиболее естественный путь -постули-ровать соответствие струнно-полевых вершин и корреляторов в конформной теории поля: 2) где Σ N -соответствующая риманова поверхность [3]. Не ясно, гарантирует ли дан-ная фиксация неопределенности выполнение условия (2.2) для всех вершин (N > 3) в башне.…”

“…One can be puzzled why we choose different maps P 2 and P 3 and may think that it gives extra relative factor between the brackets with n = 2 and n = 3. But fortunately this never happens, because Witten's vertex is invariant under the conformal group [209], so one can choose arbitrary functions P 2 and P 3 .…”

In this lecture notes we explain and discuss some ideas concerning noncommutative geometry in general, as well as noncommutative field theories and string field theories. We consider noncommutative quantum field theories emphasizing an issue of their renormalizability and the UV/IR mixing. Sen's conjectures on open string tachyon condensation and their application to the D-brane physics have led to wide investigations of the covariant string field theory proposed by Witten about 15 years ago. We review main ingredients of cubic (super)string field theories using various formulations: functional, operator, conformal and the half string formalisms. The main technical tools that are used to study conjectured D-brane decay into closed string vacuum through the tachyon condensation are presented. We describe also methods which are used to study the cubic open string field theory around the tachyon vacuum: construction of the sliver state, "comma" and matrix representations of vertices.
