t-Entropy formulae for concrete classes of transfer operators

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2019
t-Entropy is a principal object of the spectral theory of operators, generated by dynamical systems, namely, weighted shift operators and transfer operators.

Flows in Infinite-Dimensional Phase Space Equipped with a Finitely-Additive Invariant Measure

open access: yesMathematics, 2023
Finitely-additive measures invariant to the action of some groups on a separable infinitedimensional real Hilbert space are constructed. The invariantness of a measure is studied with respect to the group of shifts on a vector of Hilbert space, the ...

On the metrical theory of a non-regular continued fraction expansion

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015
We introduced a new continued fraction expansions in our previous paper. For these expansions, we show the Brodén-Borel-Lévy type formula. Furthermore, we compute the transition probability function from this and the symbolic dynamical system of the ...

Conservation Laws and Invariant Measures in Surjective Cellular Automata [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2011
We discuss a close link between two seemingly different topics studied in the cellular automata literature: additive conservation laws and invariant probability measures.

Deformation-specific and deformation-invariant visual object recognition: pose vs identity recognition of people and deforming objects [PDF]

open access: yes, 2014
When we see a human sitting down, standing up, or walking, we can recognise one of these poses independently of the individual, or we can recognise the individual person, independently of the pose. The same issues arise for deforming objects. For example,

Invariant measures and random attractors of stochastic delay differential equations in Hilbert space

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2022
This paper is devoted to a general stochastic delay differential equation with infinite-dimensional diffusions in a Hilbert space. We not only investigate the existence of invariant measures with either Wiener process or Lévy jump process, but also ...

Rotationally invariant texture based features [PDF]

open access: yes, 2001
Content-based retrieval is ultimately dependent on the features used for the annotation of data and its efficiency is dependent on the invariance and robust properties of these features.

The work of Professor Andrzej Lasota on asymptotic stability and recent progress [PDF]

open access: yesOpuscula Mathematica, 2008
The paper is devoted to Professor Andrzej Lasota's contribution to the ergodic theory of stochastic operators. We have selected some of his important papers and shown their influence on the evolution of this topic. We emphasize the role A.

New Invariant Quantity To Measure The Entanglement In The Braids

open access: yesJournal of Nigerian Society of Physical Sciences, 2022
In this work, we demonstrate  that the integral formula for a generalised Sato-Levine invariant is consistent in certain situations with Evans and Berger's formula for the fourth-order winding number.
