Some corollaries of the Hirzebruch–Thom signature theorem are discussed. The multiplicativity of the signature and the naturalness of the Pontryagin classes for coverings in the case of $\mathbb Q$-homology manifolds is proved. A geometric proof of Hirzebruch's well-known “functional equation” for the virtual signature is outlined. Bibl. 24 titles.
