DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CAvid/28/">L
 acunary polynomials in $L^1$: geometry of the unit sphere</a>\nby Konstant
 in Dyakonov (ICREA & Universitat de Barcelona\, Spain) as part of CAvid: C
 omplex Analysis video seminar\n\nLecture held in N/A.\n\nAbstract\nLet $\\
 Lambda$ be a finite set of nonnegative integers\, and let $\\mathcal P(\\L
 ambda)$ be the linear hull of the monomials $z^k$ with $k\\in\\Lambda$\, v
 iewed as a subspace of $L^1$ on the unit circle. We characterize the extre
 me and exposed points of the unit ball in $\\mathcal P(\\Lambda)$.\n
