Quantization of Non-Critical Bosonic Open String Theory
Igor Nikitin
The theory of relativistic strings is considered in frames of Hamiltonian formalism and Dirac's quantization procedure. A special gauge fixing condition is formulated, related with…

Structure of singularities on the world sheets of relativistic strings
Stanislav Klimenko, Igor Nikitin, Lialia Nikitina
We show that relativistic strings of open and closed types in Minkowski space-time of dimension 3 and 4 have topologically stable singular points. This paper describes the structur…

String theory in Lorentz-invariant time-like gauge
Igor Nikitin
A theory of closed bosonic string in time-like gauge, related in Lorentz-invariant way with the world sheet, is considered. Absence of quantum anomalies in this theory is shown.
