On the valency of a polynomial in \(H\overline H\)
The authors consider the problem of determining the maximal valency of a logarithmic polynomial, which is the product of an analytic polynomial \(p\) and the conjugate of an analytic polynomial \(q\). Among other things, they show that the maximum valency exceeds the degree of \(pq\).
