A talk on: Birkhoff Interpolation Problem: Some Old and New Results will be delivered by Prof. Geno Nikolov, Faculty of Mathematics and Informatics, Sofia University. Abstract. In 1906 George David Birkhoff formulated a general interpolation problem for algebraic polynomials (hereafter called BIP). BIP is defined in terms of incidence matrices and encompasses as particular cases the classical Lagrange and Hermite interpolation problems. In contrast with the classical cases, the general BIP is not always solvable. Despite studied by [...]
