The classification of simple Jacobi--Ricci commuting algebraic curvature tensors
P. Gilkey, S. Nikcevic
We classify algebraic curvature tensors such that the Ricci operator is simple (i.e. the Ricci operator is complex diagonalizable and either the complex spectrum consists of a sing…
Hyperelliptic Jacobians as Billiard Algebra of Pencils of Quadrics: Beyond Poncelet Porisms
Vladimir Dragovic, Milena Radnovic
The thirty years old programme of Griffiths and Harris of understanding higher-dimensional analogues of Poncelet-type problems and synthetic approach to higher genera addition theo…
Noncommutative Minisuperspace Cosmology
Aleksandar Zejak, Branko Dragovich
We consider the noncommutative minisuperspace classical and quantum cosmologies.
Derivation of the quantum probability law from minimal non-demolition measurement
Fedor Herbut
One more derivation of the quantum probability rule is presented in order to shed more light on the versatile aspects of this fundamental law. It is shown that the change of state…
