Abstract:  

An order d rigidity inequality for a smooth function f is an explicit
lower bound for the (d+1)-st derivatives of f, which holds, if f
exhibits certain patterns, forbidden for polynomials of degree d. 

We discuss some recent results in this direction, which use as an input
the ``density'' of the zero set Z of f, or, in contrast, its topology.
In particular, we interpret in terms of rigidity inequalities some
recent results of Lerario and Stecconi, comparing topology of smooth
transversal singularities, and of their polynomial approximations.
