On a q-analogue of the multiple gamma functions

A $q$-analogue of the multiple gamma functions is introduced, and is shown to satisfy the generalized Bohr-Morellup theorem. Furthermore we give some expressions of these function.Comment: 8 pages, AMS-Late

On the Cauchy problem for the debar operator

We present new results concerning the solvability, of lack thereof, in the Cauchy problem for the debar operator, with initial values assigned on a weakly pseudoconvex hypersurface, and provide illustrative examples.Comment: This is the final version, which is appearing in Arkiv foer Mathemati

Non-accretive Schrödinger operators and exponential decay of their eigenfunctions

International audienceWe consider non-self-adjoint electromagnetic Schrödinger operators on arbitrary open sets with complex scalar potentials whose real part is not necessarily bounded from below. Under a suitable sufficient condition on the electromagnetic potential, we introduce a Dirichlet realisation as a closed densely defined operator with non-empty resolvent set and show that the eigenfunctions corresponding to discrete eigenvalues satisfy an Agmon-type exponential decay

The Early Royal Society and Visual Culture

Recent studies have fruitfully examined the intersection between early modern science and visual culture by elucidating the functions of images in shaping and disseminating scientific knowledge. Given its rich archival sources, it is possible to extend this line of research in the case of the Royal Society to an examination of attitudes towards images as artefacts –manufactured objects worth commissioning, collecting and studying. Drawing on existing scholarship and material from the Royal Society Archives, I discuss Fellows’ interests in prints, drawings, varnishes, colorants, images made out of unusual materials, and methods of identifying the painter from a painting. Knowledge of production processes of images was important to members of the Royal Society, not only as connoisseurs and collectors, but also as those interested in a Baconian mastery of material processes, including a “history of trades”. Their antiquarian interests led to discussion of painters’ styles, and they gradually developed a visual memorial to an institution through portraits and other visual records.AH/M001938/1 (AHRC

Ensaios teóricos: os capitulos introdutórios de Henry Fielding Exploring theory: Fielding’s prefatory chapters

Henry Fielding, um dos fundadores do romance inglês, deixou um material teórico bastante rico a respeito do gênero em ascensão, que ele discutiu em prefácios e nos célebres capítulos introdutórios a Tom Jones. Esse artigo tem como objetivo apresentar alguns dos impasses e dilemas enfrentados pelo romancista e as soluções formais que ele propôs para resolvê-los.<br>Henry Fielding, one of the founders of the English novel, has left a wealth theoretical material about the rising genre, which he discussed in prefaces and in his famous introductory chapters to Tom Jones, this article aims to present some of the impasses and double binds faced by the novelist and the formal solutions he proposed to deal with them
