The classical approach to the study of xed point semantics of deenite logic programs P utilises two main facts : (1) The set I J L of all interpretations of the underlying language L based on a given preinterpretation J forms a complete lattice under the partial order of set inclusion. (2) The immediate consequence map T P deened on I J L is lattice continuous. An application is then made of a ...

In this paper, we will use the differential equations of SIR model as a non-linear system, by using Runge-Kutta numerical method to calculate simulated values for known epidemiological diseases related time series including epidemic disease COVID-19, obtain hypothetical results and compare them with dailyreal statisticals counties world know behavior through mathematical applications, in terms ...
