La trasfigurazione del principio di legalità penale statale nel prisma del diritto europeo

2012

Il contributo esamina l’ormai risalente questione del possibile contrasto del diritto penale di fonte europea con il principio di legalità penale statale, alla luce delle novità introdotte dal Trattato di Lisbona. In particolare, esso evidenzia come la definitiva attribuzione di una competenza penale (pur sempre indiretta) all’Unione da parte del nuovo assetto istituzionale introdotto a Lisbona non abbia irreparabilmente compromesso l’esito del suddetto contrasto, nei termini negativi o di un’inevitabile capitolazione delle garanzie della legalità penale, o viceversa, del necessario innalzamento della barriera dei controlimiti contro il rischio di tale capitolazione. In proposito, lo scritt…

Optimal Population Growth as an Endogenous Discounting Problem: The Ramsey Case

2018

International audience; This paper revisits the optimal population size problem in a continuous time Ramsey setting with costly child rearing and both intergenerational and intertemporal altruism. The social welfare functions considered range from the Millian to the Benthamite. When population growth is endogenized, the associated optimal control problem involves an endogenous effective discount rate depending on past and current population growth rates, which makes preferences intertemporally dependent. We tackle this problem by using an appropriate maximum principle. Then we study the stationary solutions (balanced growth paths) and show the existence of two admissible solutions except in…

Infinite games and chain conditions

2015

We apply the theory of infinite two-person games to two well-known problems in topology: Suslin's Problem and Arhangel'skii's problem on $G_\delta$ covers of compact spaces. More specifically, we prove results of which the following two are special cases: 1) every linearly ordered topological space satisfying the game-theoretic version of the countable chain condition is separable and 2) in every compact space satisfying the game-theoretic version of the weak Lindel\"of property, every cover by $G_\delta$ sets has a continuum-sized subcollection whose union is $G_\delta$-dense.

Dirichlet Forms, Poincaré Inequalities, and the Sobolev Spaces of Korevaar and Schoen

2004

We answer a question of Jost on the validity of Poincare inequalities for metric space-valued functions in a Dirichlet domain. We also investigate the relationship between Dirichlet domains and the Sobolev-type spaces introduced by Korevaar and Schoen.

Restricted Uniform Boundedness in Banach Spaces

2009

Precise conditions for a subset A of a Banach space X are known in order that pointwise bounded on A sequences of bounded linear functionals on X are uniformly bounded. In this paper, we study such conditions under the extra assumption that the functionals belong to a given linear subspace &#915 of X *. When &#915 = X *, these conditions are known to be the same ones assuring a bounded linear operator into X , having A in its image, to be onto. We prove that, for A , deciding uniform boundedness of sequences in &#915 is the same property as deciding surjectivity for certain classes of operators.

Fixed point theory for a class of generalized nonexpansive mappings

2011

AbstractIn this paper we introduce two new classes of generalized nonexpansive mapping and we study both the existence of fixed points and their asymptotic behavior.
