Learning with computer simulations: a case study on reservoir temperatures in carnot cycles

open access: yesInvestigações em Ensino de Ciências
Computer simulations have played a significant role in the development of physics, and in physics education as well. Researchers have addressed whether simulations promote learning, but few studies have investigated how simulations actually participate ...

Double ball property: an overview and the case of step two Carnot groups

open access: yesBruno Pini Mathematical Analysis Seminar, 2012
We investigate the notion of the so-called Double Ball Property, which concerns the nonnegative sub-solutions of some differential operators. Thanks to the axiomatic approach developed in [6], this is an important tool in order to solve the Krylov ...

Coercive inequalities on Carnot groups: taming singularities

open access: yesAnalysis and Mathematical Physics
AbstractIn the setting of Carnot groups, we propose an approach of taming singularities to get coercive inequalities. To this end, we develop a technique to introduce natural singularities in the energy function U in order to force one of the coercivity conditions.
