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…
Genome of Descartes Folium via Normalization
Adrian Constantinescu, Constantin Udriste, Steluta Pricopie
The Folium of Descartes in carries group laws, defined entirely in terms of algebraic operations over the field . The problems discussed in…
Optimal control on distributions
Constantin Udriste
This paper studies (single-time and multitime) optimal control problems on a nonholonomic manifold (described either by the kernel of a Gibbs-Pfaff form or by the span of appropria…
