By using the theory of the principal function of a hyponormal operator with rank-one self-commutator, one classifies some extremal points of the solutions of the truncated L-problem of moments in two real variables. These extremal elements, called degenerated solutions of the L-problem, are proved t
The extremal solutions of the truncated L-problem of moments in two real variables, with support included in a given compact set, are described as characteristic functions of semi-algebraic sets given by a single polynomial inequality. An exponential kernel, arising as the determinantal function of
