Invariant critical sets of conserved quantities
, 2011 For a dynamical system we will construct various invariant sets starting from its conserved quantities. We will give conditions under which certain solutions of a nonlinear system are also solutions for a simpler dynamical system, for example when they ...

Positivity in the presence of initial system-environment correlation [PDF]
, 2012 The constraints imposed by the initial system-environment correlation can lead to nonpositive Dynamical maps. We find the conditions for positivity and complete positivity of such dynamical maps by using the concept of an assignment map.

Dynamic Reasoning Systems [PDF]
ACM Transactions on Computational Logic, 2015 A dynamic reasoning system (DRS) is an adaptation of a conventional formal logical system that explicitly portrays reasoning as a temporal activity, with each extralogical input to the system and each inference rule application being viewed as occurring at a distinct timestep.

The Optimal Balance between Oncolytic Viruses and Natural Killer Cells: A Mathematical Approach
Mathematics, 2022 Oncolytic virotherapy (OV) is a cancer therapy utilizing lytic viruses that specifically target cancer cells for elimination. In this relatively new therapy, two contradictory observations have been made.

The conflict triad dynamical system
, 2010 A dynamical model of the natural conflict triad is investigated. The conflict interacting substances of the triad are: some biological population, a living resource, and a negative factor (e.g., infection diseases).

On the Dynamics of Systems of Urns [PDF]
Discrete Mathematics & Theoretical Computer Science, 2015 In this paper we present an analysis of some generalization of the classic urn and balls model. In our model each urn has a fixed capacity and initially is filled with white balls. Black balls are added to the system of connected urns and gradually displace white balls.

Dynamical behavior of a general non-autonomous dynamical system
Applied General TopologyIn this work, we investigate dynamical notions such as minimality, almost periodicity, equicontinuity, transitivity, proximality and periodicity for a general non-autonomous dynamical system.
