Special solutions of nonlinear von Neumann equations
Jan Naudts, Maciej Kuna
We consider solutions of the non-linear von Neumann equation involving Jacobi's elliptic functions sn, cn, and dn, and 3 linearly independent operators. In two cases one can constr…
Continuity of a class of entropies and relative entropies
Jan Naudts
The present paper studies continuity of generalized entropy functions and relative entropies defined using the notion of a deformed logarithmic function. In particular, two distinc…
Operator formalism of quantum mechanics
Jan Naudts
This is the first chapter of a new and unconventional textbook on quantum mechanics and quantum field theory. The chapter introduces standard quantum mechanics by means of a symmet…
C*-Multipliers, crossed product algebras, and canonical commutation relations
Jan Naudts
The notion of a multiplier of a group X is generalized to that of a C*-multiplier by allowing it to have values in an arbitrary C*-algebra A. On the other hand, the notion of the a…
