Comments on the string theory

  • Published:
Il Nuovo Cimento B (1971-1996)

Summary

In this article I make some comments on the string theory. In particular, I propose to unify the world surface metricg ab(ξa) and the target space-time metricG ΜΝ(xα) with a unified metricG ΜΝ ab(xα(ξc), ξd) which in some special case may be separable,G abΜΝ = √-ggabGΜΝ.
