The measure in three dimensional Nambu - Goto string theory
We show that the measure of the three dimensional Nambu-Goto string theory has a simple decomposition as a measure on two parameter group of induced areapreserving transformations of the immersed surface and a trivial measure for the area of the surface.

متن کاملHidden symmetries of the Nambu-Goto action
ABSTRACT We organize the eight variables of the four-dimensional bosonic string (Ẋ, X ) into a 2×2×2 hypermatrix aAA′A′′ and show that in signature (2, 2) the Nambu-Goto Lagrangian is given by √ Det a where Det is Cayley’s hyperdeterminant. This is invariant not only under [SL(2, R)] but also under interchange of the indices A, A and A. This triality reveals hitherto hidden discrete symmetries ...
متن کاملThe Invariant Charges of the Nambu–Goto String Theory: Quantization of Non-Additive Composition Laws
We examine and implement the concept of non-additive composition laws in the quantum theory of closed bosonic strings moving in (3 + 1)-dimensional Minkowski space. Such laws supply exact selection rules for the merging and splitting of closed strings.
متن کاملThe Nambu – Goto Theory of Closed Bosonic Strings Moving in 1 + 3 – Dimensional Minkowski Space
A relevant part of the quantum algebra of observables for the closed bosonic strings moving in 1 + 3–dimensional Minkowski space is presented in the form of generating relations involving still one, as yet undetermined, real free parameter.
متن کاملW∞ Symmetry of the Nambu–goto String in 4 Dimensions
We consider a bosonic string propagating in 4–dimMinkowski space. We show that in the orthonormal gauge the classical system exhibits a hidden W∞ chiral symmetry, arising from the equivalence of its transverse modes with the SU(2)/U(1) coset model defined on the string world–sheet. Generalizations to other string backgrounds are proposed. We also define a Liouville–like transformation that maps...
