Measure-theoretic rigidity for Mumford curves [PDF]

open access: yes, 2012
One can describe isomorphism of two compact hyperbolic Riemann surfaces of the same genus by a measure-theoretic property: a chosen isomorphism of their fundamental groups corresponds to a homeomorphism on the boundary of the Poincaré disc that is ...

Coarse graining as a representation change

open access: yesPhysics Letters B, 2019
We discuss how SU(1,1) coherent states from the discrete series allow for a natural coarse graining operation. The physical application is quantum theories based on a set of three extensive observables whose Poisson algebra is isomorphic to su(1,1).

Algebraic and model theoretic methods in constraint satisfaction

open access: yesCoRR, 2015
This text is related to the tutorials I gave at the Banff International Research Station and within a "Doc-course" at Charles University Prague in the fall of 2014. It describes my current research and some of the most important open questions related to it.

Modelling the influence of RKIP on the ERK signalling pathway using the stochastic process algebra PEPA [PDF]

open access: yes, 2006
This paper examines the influence of the Raf Kinase Inhibitor Protein (RKIP) on the Extracellular signal Regulated Kinase (ERK) signalling pathway [5] through modelling in a Markovian process algebra, PEPA [11].

Some properties of Morly rank over Jonsson sets

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2016
This article introduced and discussed the concepts of minimal Jonsson sets and respectively strongly minimal Jonsson sets. On this basis, it introduces the concept of the independence of special subsets of existentially closed submodel of the semantic ...

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems

open access: yesInternational Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.
A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

Topos-Theoretic Approaches to Quantum Theory [PDF]

open access: yes, 2012
Starting from a naive investigation into the nature of experiments on a physical system one can argue that states of the system should pair non-degenerately with physical observables. This duality is closely related to that between space and quantity, or,

Toward formal development of programs from algebraic specifications: Model-theoretic foundations [PDF]

open access: yes, 1992
This paper presents in an informal way the main ideas underlying our work on the model-theoretic foundations of algebraic specification and program development. We attempt to offer an overall view, rather than new results, and focus on the basic motivation behind the technicalities presented elsewhere and on the conclusions from this work.
