>VITAE: Maxim Raginsky was born in 1977 in Vladimir, Russia. He obtained his PhD in 2002 from Northwestern University (Evanston, Illinois, USA), where he is presently a posdoctoral fellow with the Center for Photonic Communication and Computing. His current research interests include classical and quantum information theory, C*-algebraic methods for quantum information, and applied probability theory.
Abstract
	I shall discuss a well-known theorem of the Radon-Nikodym type that gives a necessary and sufficient condition for one completely positive (CP) map to possess a unique positive operator-valued density with respect to another, along with some of its corollaries, such as the Lebesgue decomposition of one CP map with respect to another. I shall then concentrate on the significance and application of these mathematical results in the context of quantum information theory.
