Field-theory approach for strings
A.A. Tsei-brevetlin · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 1986
An approach to string theory is developed on the basis of a covariant effective action for fields corresponding to the excitation modes of the string. Both closed and open bosonic strings are considered. A low-energy approximation to the effective action is derived and the structure of the interactions of the dilation field is established.
