... those indices. Thus, if S µνρ = S νµρ , (1.64) we say that S µνρ is symmetric in its first two indices, while if S µνρ = S µρν = S ρµν = S νµρ = S νρµ = S ρνµ , (1.65) we say that S µνρ is symmetric ... vector is an abstract geometrical entity, while the components are just the coefficients of the basis vectors in some convenient basis.

For the closed string the spectrum contains also two other massless fields: the ... it becomes massless. Although we will still call this mode “tachyon”, strictly speaking, it represents a good massless field describing the st able vacuum of the two-dimensional bosonic string theor...
