Query: A question by Alexei Aleksandrov and logarithmic determinants   We answer negatively to the question posed by Aleksandrov concerning analytic
functions of Smirnov's class in the unit disk with pure imaginary boundary
values. We also find new sufficient conditions for representations of functions
of Smirnov's class by the Schwartz and Cauchy integrals. These conditions
extend a previous result of Aleksandrov.
