Let G be a fixed connected multigraph with no loops. A random n-lift of G is obtained by replacing each vertex of G by a set of n vertices (where these sets are pairwise disjoint) and replacing each edge by a randomly chosen perfect matching between the n-sets corresponding to the endpoints of the edge. Let XG be the number of perfect matchings in a random lift of G. We study the distribution of XG in the limit as n tends to infinity, using the small subgraph conditioning method.We present several results including an asymptotic formula for the expectation of XG when G is d-regular, d ≥ 3. The interaction of perfect matchings with short cycles in random lifts of regular multigraphs is also analysed. Partial calculations are performed for the second moment of XG, with full details given for two example multigraphs, including the complete graph K4.To assist in our calculations we provide a theorem for estimating a summation over multiple dimensions using Laplace's method. This result is phrased as a summation over lattice points, and may prove useful in future applications.

We prove an asymptotic formula for the second moment (up to height T) of the Riemann zeta function with two shifts. The case we deal with is where the real parts of the shifts are very close to zero and the imaginary parts can grow up to T2-ε, for any ε > 0.

Let [Formula: see text] be the argument of the Riemann zeta-function at the point [Formula: see text]. For [Formula: see text] and [Formula: see text] define its antiderivatives as [Formula: see text] where [Formula: see text] is a specific constant depending on [Formula: see text] and [Formula: see text]. In 1925, Littlewood proved, under the Riemann Hypothesis (RH), that [Formula: see text] for [Formula: see text]. In 1946, Selberg unconditionally established the explicit asymptotic formulas for the second moments of [Formula: see text] and [Formula: see text]. This was extended by Fujii for [Formula: see text], when [Formula: see text]. Assuming the RH, we give the explicit asymptotic formula for the second moment of [Formula: see text] up to the second-order term, for [Formula: see text]. Our result conditionally refines Selberg’s and Fujii’s formulas and extends previous work by Goldston in [Formula: see text], where the case [Formula: see text] was considered.

We study the tail behavior of discounted aggregate claims in a continuous-time renewal model. For the case of Pareto-type claims, we establish a tail asymptotic formula, which holds uniformly in time.

Crime et Châtiment raconte l’histoire de Raskolnikov à l’été 1865 à Petersbourg, qui assassine une vieille usurière et sa sœur. Dès avant son geste Raskolnikov se met au travail quant aux questions de la culpabilité, du châtiment et de la rédemption. Le texte présente la folie humaine selon deux modalités, la névrose et la psychose, chacune avec ses deux temporalités, c’est-à-dire un premier moment de conscience d’une séparation d’avec la réalité, et un second moment de séparation effective. Raskolnikov se trouve du côté de la psychose, sur un continuel point de basculement entre les deux temps et les folies de Catherina Ivanovna et, peut-être, d’Arcady Svidrigaïlov, se trouvent du côté de la névrose, avec seul Arcady qui ne bascule pas. La seconde idée est celle de l’enjeu du crime : peut-on se trouver parmi ses frères humains de cet amour inconditionnel qui serait capable d’aimer le criminel le plus abject ? Le paradoxe est que Raskolnikov, qui ne peut supporter la transgression au point de délirer une race pure, met au défi ce monde à aimer le coupable du crime le plus vil. Nous terminerons en proposant que l’amour ne puisse être qu’inconditionnel, même s’il ne peut être illimité.

Laurent Dubreuil provocatively proposes an extremist rethinking of the limits of politics – toward a break from politics, the political and policies. Rather than yet another re-articulation, he calls for a refusal of politics, suggesting a form of apolitics that would make our lives more liveable. The first chapter situates the refusal of politics in relation to different contemporary theoretical attempts to renew politics, and makes the case for a greater rupture. The second moment takes up what is liveable in life by way of apolitical experience, in contrast to appropriations of the collective, including a discussion of the arts. Finally, Dubreuil draws up an incomplete inventory of means: forms of existence – often frail and fleeting – that make an exit toward atopia.
