This thesis studies a modified oscillator quantization of the bosonic string, in which the time like sector is quantized with the opposite choice of creation and annihilation operators. The aim is to analyze the resulting Fock space, prove positivity of the kinematical inner product, and study the modified Virasoro algebra. In particular, the construction leads to an effective matter central charge c=D-2, giving c=24 in D=26.

Abstract
This thesis studies a modified oscillator quantization of the bosonic string, in which the time like sector is quantized with the opposite choice of creation and annihilation operators. The aim is to analyze the resulting Fock space, prove positivity of the kinematical inner product, and study the modified Virasoro algebra. In particular, the construction leads to an effective matter central charge c=D-2, giving c=24 in D=26.| File | Dimensione | Formato | |
