I shall review some aspects of the relationship between scale and conformal invariance in 2-dimensional sigma models. Then, I shall explain how such an investigation is related to the Perelman's ideas of proving the Poincare' conjecture. Using this, I shall demonstrate that scale invariant sigma models with B-field coupling and compact target space are conformally invariant. Several examples will also be presented that elucidate the results. The talk is based on the arXiv paper 2404.19526.
