Three derivations of critical dimension in string theory
I shall discuss various approaches to quantization of the free bosonic string theory. I shall also show that the critical dimension D=26 arises due to the cancellation of various anomalies (Lorentz, conformal, Weyl) depending on the quantization scheme.
