Flatness produced by some geometric PDEs
Iulia Hirica, Constantin Udriste, Gabriel Pripoae +1
This paper has several goals. The first idea is to study the geometric PDEs of connection-flatness, curvature-flatness, Ricci-flatness, scalar curvature-flatness in a modern and ri…
Geobiodynamics and Roegenian Economic Systems
Constantin Udriste, Massimiliano Ferrara, Dorel Zugravescu +2
This mathematical essay brings together ideas from Economics, Geobiodynamics and Thermodynamics. Its purpose is to obtain real models of complex evolutionary systems. More specific…
Economic Cycles of Carnot Type
Constantin Udriste, Vladimir Golubyatnikov, Ionel Tevy
Originally, the Carnot cycle is a theoretical thermodynamic cycle that provides an upper limit on the efficiency that any classical thermodynamic engine can achieve during the conv…
Phase Diagram for Roegenian Economics
Constantin Udriste, Massimiliano Ferrara, Ionel Tevy +2
We recall the similarities between the concepts and techniques of Thermodynamics and Roegenian Economics. The Phase Diagram for a Roegenian economic system highlights a triple poin…
Multitime hybrid differential games with multiple integral functional
Constantin Udrişte, Elena-Laura Otobîcu, Ionel Ţevy
A multiple integral functional is equivalent to a curvilinear integral functional, if the domain is a hyper-parallelepiped, but equivalence is only theoretical. The introduction of…
Periodic linear discrete multitime diagonal recurrence with application in economics
Cristian Ghiu, Raluca Tuliga, Constantin Udriste +1
Floquet theory, first published in 1883 for periodic linear differential equations, is extended in this paper to multitime diagonal recurrences. We find explicitly a monodromy matr…
