Fisher Information as General Metrics of Quantum Synchronization
Entropy, 2023 Quantum synchronization has emerged as a crucial phenomenon in quantum nonlinear dynamics with potential applications in quantum information processing. Multiple measures for quantifying quantum synchronization exist. However, there is currently no widely agreed metric that is universally adopted.

Solving an Integral Equation via Tricomplex-Valued Controlled Metric Spaces
Axioms, 2023 In this present study, we propose the concept of tricomplex-controlled metric spaces as a generalization of both controlled metric-type spaces and tricomplex metric-type spaces.

Characterizing (non-)Markovianity through Fisher information
SciPost Physics, 2023 A non-isolated physical system typically loses information to its environment, and when such loss is irreversible the evolution is said to be Markovian.

The Volume of Two-Qubit States by Information Geometry
Entropy, 2018 Using the information geometry approach, we determine the volume of the set of two-qubit states with maximally disordered subsystems. Particular attention is devoted to the behavior of the volume of sub-manifolds of separable and entangled states with ...

Detection of image structures using the Fisher information and the Rao metric [PDF]
, 2004 In many detection problems, the structures to be detected are parameterized by the points of a parameter space. If the conditional probability density function for the measurements is known, then detection can be achieved by sampling the parameter space ...

Optical flow estimation using the Fisher–Rao metric [PDF]
Neuromorphic Computing and Engineering, 2021 Abstract The optical flow in an event camera is estimated using measurements in the address event representation (AER). Each measurement consists of a pixel address and the time at which a change in the pixel value equalled a given fixed threshold.

F-Geometry and Amari’s α-Geometry on a Statistical Manifold
Entropy, 2014 In this paper, we introduce a geometry called F-geometry on a statistical manifold S using an embedding F of S into the space RX of random variables. Amari’s α-geometry is a special case of F-geometry.

Some related fixed point theorems for multivalued mappings on two metric spaces
Karpatsʹkì Matematičnì Publìkacìï, 2020 The definition of related mappings was introduced by Fisher in 1981. He proved some theorems about the existence of fixed points of single valued mappings defined on two complete metric spaces and relations between these mappings.
