Abstract [en]

We construct a region with infinitely many cusps on its boundary such that it is possible to estimate the derivative of a conformal mapping of the units disk onto this region from below. We use some ideas taken from the construction of a famous Keldysh-Lavrentiev example. Bibliography: 2 titles.
