Description
I will talk about linear extremal problems in the classes of nonvanishing bounded analytic functions defined in the unit disk centered at the origin. It turns out extremal values in the class of nonvanishing bounded analytic functions can be estimated with the sharp constant $2/e$ from below via extremal values in the whole class of bounded analytic functions.
