Pointwise error estimate for a noncoercive system of quasi-variational inequalities related to the management of energy production.
P-order necessary and sufficient conditions for optimality in singular calculus of variations
This paper is devoted to singular calculus of variations problems with constraint functional not regular at the solution point in the sense that the first derivative is not surjective. In the first part of the paper we pursue an approach based on the constructions of the p-regularity theory. For p-regular calculus of variations problem we formulate and prove necessary and sufficient conditions for optimality in singular case and illustrate our results by classical example of calculus of variations...

Pricing rules under asymmetric information
We consider an extension of the Kyle and Back's model [Back, Rev. Finance Stud.5 (1992) 387–409; Kyle, Econometrica35 (1985) 1315–1335], meaning a model for the market with a continuous time risky asset and asymmetrical information. There are three financial agents: the market maker, an insider trader (who knows a random variable V which will be revealed at final time) and a non informed agent. Here we assume that the non informed agent is strategic, namely he/she uses a utility function to...

Problemi di regolarità per un nuovo tipo di funzionale del calcolo delle variazioni
Si considerano questioni riguardanti la regolarità delle soluzioni di problemi di minimo di funzionali che coinvolgono sia termini di volume che di superficie. Si danno indicazioni sui risultati attesi in alcuni casi di notevole interesse, collegati a problemi di segmentazione di immagini e alla teoria dei cristalli liquidi.
