**Title:**

*Variations on Mazur-Ulam theorem*

Roman Sznajder

**Speaker:**

**Abstract**

The classical Mazur-Ulam theorem states that every isometry

*g*of one real normed space onto another such that

*g*(0) = 0 is a bounded linear operator.

We will give at least two various proof (time permits): one classical (Mazur-Ulam 1932), another by Figiel, Šemrl, Väisälä (2002) using entirely different methods. We will also mention some generalizations.
