Isoperimetric inequalities in Euclidean convex bodies
In this paper we consider the problem of minimizing the relative perimeter
under a volume constraint in the interior of a convex body, i.e., a compact
convex set in Euclidean space with interior points. We shall not impose any
regularity assumption on the boundary of the convex set. Amongst other results,
we shall prove the equivalence between Hausdorff and Lipschitz convergence, the
continuity of the isoperimetric profile with respect to the Hausdorff
distance,and the convergence in Hausdorff distance of sequences of
isoperimetric regions and their free boundaries. We shall also describe the
behavior of the isoperimetric profile for small volume, and the behavior of
isoperimetric regions for small volume.Comment: Final version. References and a dedication adde

Performative betrayals: Christian gender politics or Christianity on trial in Oscar Wilde's Salomé
Oscar Wildeâs symbolist drama SalomĂ© (1892) was written directly in French, a language the playwright âadore[d] without speaking it wellâ (Ellmann). In order to avoid awkward phrasing in the dialogues, Wilde minimized the importance of language in favour of the show. In consequence in SalomĂ© silence is at least as important as speech, and showing or suggesting through performance makes up for telling. The eponymous heroine is therefore mainly shaped by quotations. These are either stated by third characters or âtranslatedâ into images through performance. The enunciated quotations epitomize the male charactersâ gaze while the âperformedâ ones, which are actually scraps and bits from Biblical, Greek and Roman myths, are more inherent with Salomeâs âessential natureâ. Consequently, in this gender-oriented drama, SalomĂ© appears as a discursive and plastic construct which brings together male representations of the feminine as both an ideal and a threat (notably the 19th century myth of the femme fatale) as well as performative evocations of archetypal female characters (such as Isis, Ishtar). The above characterization process aims at opposing two versions of a Janus-faced SalomĂ©, whose identity can either be a manâs issue lying outside her control , or an embodiment of the archetypal matriarchal female. In both cases, SalomĂ© functions as a self conscious postmodern construct whose self is shaped by texts and narratives.Â
However, when Herod is imploring her not to listen to her mother and to ask for something else than Jokanaanâs head, she answers: âIt is not my motherâs voice that I heed. It is for mine own pleasure that I ask the head of Jokanaanâ. By so doing, SalomĂ© breaks with the tradition she stems from, both biblical and mythological, and attempts to start a new one in which pleasure becomes a yardstick by which she defines herself for us who are invited to use it, too, in order to redefine identity and gender.
