Proceedings of the 3rd Microconference Analytic and Algebraic Methods III (June 19, 2007, Prague, Czech Republic).
The Guest Editor for this special issue is Miloslav Znojil The 3rd continuation of the series of the oneday conferences ''Analytic and Algebraic Methods in Physics'' took place in Villa Lanna in Prague, Czech Republic, during June 19, 2007. As one of the frequent, albeit irregular, meetings organized by the members of the Doppler Institute for mathematical physics and applied mathematics joining several academic institutions in Prague, Rez and Hradec Kralove, our international ''microconference'' narrowed the active interest of its 27 participants, this time, to a few open problems in Quantum Mechanics and in Quantum Field Theory. In more detail let me summarize that the nine plenary lectures paid attention to the mathematical properties of the integrable, quasihermitian, separable, quaternionic or singular operators of observables as well as to the more specific questions concerning functional determinants and topological theories. The new concepts of quantum information, of spin filtering and of the projective Hilbertspace structures were discussed. In a search for an appropriate medium for leaving a more lasting impact upon the broader scientific community some of the participants really appreciated finding the SIGMA as a medium which seems to combine the pleasingly high standards of the rigorous though still amazingly speedy refereeing of the written form of the presentation of the topical and original new results with an extreme easiness of their webmediated accessibility to the interested audience. In this sense, the enthusiasm and the encouragement of the project of these compact and handy ''microproceedings" as well as the perceivable amount of the real help offered by the editorial team of the SIGMA is to be gratefully acknowledged, indeed.
