Decoherent histories on graphs
R. F. Blute, I. T. Ivanov, P. Panangaden
The consistent histories approach to quantum mechanics is traditionally based on linearly ordered sequences of events. We extend the histories formalism to sets of events whose cau…
Discrete Quantum Causal Dynamics
R. Blute, I. T. Ivanov, P. Panangaden
We give a mathematical framework to describe the evolution of an open quantum systems subjected to finitely many interactions with classical apparatuses. The systems in question ma…
Supersymmetric sigma-models, twistors, and the Atiyah-Hitchin metric
I. T. Ivanov, M. Rocek
The Legendre transform and its generalizations, originally found in supersymmetric sigma-models, are techniques that can be used to give constructions of hyperkahler metrics. We gi…
sl(N) Onsager's Algebra and Integrability
D. Uglov, I. Ivanov
We define an analog of Onsager's Algebra through a finite set of relations that generalize the Dolan Grady defining relations for the original Onsager's Algebra. This inf…
Complex Structures, Duality, and WZW-Models in Extended Superspace
Ivan T. Ivanov, Byungbae Kim, Martin Rocek
We find the complex structure on the dual of a complex target space. For systems, we prove that the space orthogonal to the kernel of the commutator of the left and right…
New N=4 Superfields and Sigma-models
I. T. Ivanov, U. Lindstrom, M. Rocek
In this note, we construct new representations of D=2, N=4 supersymmetry which do not involve chiral or twisted chiral multiplets. These multiplets may make it possible to circumve…
