Rigorous Axiomatic Definition of Entropy Valid Also For Non-Equilibrium States
No full textWe present a rigorous logical scheme for the definition of entropy, based on operative
definitions of all the concepts employed, with all assumptions declared explicitly. Our treatment
is an equivalent variation of the general definition of entropy given in E.P. Gyftopoulos and G.P.
Beretta, Thermodynamics. Foundations and Applications, Dover, Mineola, 2005. However, here we
outline the minimal set of definitions and assumptions required to construct the same definition by
the most direct and essential sequence of logical steps

Numerical detection of instability regions for delay models with delay dependent parameters
No full textIn this paper we are interested in gaining local stability insights about the interior equilibria of delay models arising in biomathematics. The models share the property that the corresponding characteristic equations involve delay-dependent coefficients. The presence of such dependence requires the use of suitable criteria which usually makes the analytical work harder so that numerical techniques must be used. Most existing methods for studying stability switching of equilibria fail when applied to such a class of delay models. To this aim, an efficient criterion for stability switches was recently introduced in [E. Beretta, Y. Kuang, Geometric stability switch criteria in delay differential systems with delay dependent parameters, SIAM J. Math. Anal. 33 (2002) 1144-1165] and extended [E. Beretta, Y. Tang, Extension of a geometric stability switch criterion, Funkcial Ekvac 46(3) (2003) 337-361]. We describe how to numerically detect the instability regions of positive equilibria by using such a criterion, considering both discrete and distributed delay models
