The Dramatic Function of the Gravediggers\u27 Scene in Hamlet

It is unfortunate that one of the scenes most often cut from contemporary productions of Hamlet is the first scene of Act V, the gravediggers\u27 scene. The scene is, after all, static; it is merely a lyrical passage which seems, at first, to delay the movement of the drama, and, at all events, to add nothing to it. The producer wants swift, forward-moving action, and, certainly, he finds little enough of what he wants in the almost perverse, but always fundamental, deliberateness of this play. Consequently, one of the first scenes to be eliminated is almost invariably this one, despite its trenchant, laconic prose, its macabre humor, and its mordant, cynical philosophy of ultimate disillusion. The scene, in itself, as a separate entity, is probably one of the most famous in Shakespeare. Certainly it contains the most often misquoted line in English literature ( Alas, poor Yorick, I knew him, Horatio. ), as well as one of the funniest ( \u27Twill not be seen in him there (England); there the men are as mad as he. ). Perhaps the contemporary producer is short-sighted in cutting out the gravediggers\u27 scene; perhaps it does contribute, very definitely, to the tragedy, apart from its intrinsic excellence

Photovoltaic Oscillations Due to Edge-Magnetoplasmon Modes in a Very-High Mobility 2D Electron Gas

Using very-high mobility GaAs/AlGaAs 2D electron Hall bar samples, we have experimentally studied the photoresistance/photovoltaic oscillations induced by microwave irradiation in the regime where both 1/B and B-periodic oscillations can be observed. In the frequency range between 27 and 130 GHz we found that these two types of oscillations are decoupled from each other, consistent with the respective models that 1/B oscillations occur in bulk while the B-oscillations occur along the edges of the Hall bars. In contrast to the original report of this phenomenon (Ref. 1) the periodicity of the B-oscillations in our samples are found to be independent of L, the length of the Hall bar section between voltage measuring leads.Comment: 4 pages, 4 figure

Microwave photoresistance of a high-mobility two-dimensional electron gas in a triangular antidot lattice

The microwave (MW) photoresistance has been measured on a high-mobility two-dimensional electron gas patterned with a shallow triangular antidot lattice, where both the MW-induced resistance oscillations (MIRO) and magnetoplasmon (MP) resonance are observed superposing on sharp commensurate geometrical resonance (GR). Analysis shows that the MIRO, MP, and GR are decoupled from each other in these experiments.Comment: 5 pages, 4 figures, paper accepted by PR

General Solution Of Linear Vector Supersymmetry

We give the general solution of the Ward identity for the linear vector supersymmetry which characterizes all topological models. Such solution, whose expression is quite compact and simple, greatly simplifies the study of theories displaying a supersymmetric algebraic structure, reducing to a few lines the proof of their possible finiteness. In particular, the cohomology technology usually involved for the quantum extension of these theories, is completely bypassed. The case of Chern-Simons theory is taken as an example.Comment: 18 pages, LaTeX, no figure

Let's Twist Again: N=2 Super Yang Mills Theory Coupled To Matter

We give the twisted version of N=2 Super Yang Mills theory coupled to matter, including quantum fields, supersymmetry transformations, action and algebraic structure. We show that the whole action, coupled to matter, can be written as the variation of a nilpotent operator, modulo field equations. An extended Slavnov-Taylor identity, collecting gauge symmetry and supersymmetry, is written, which allows to define the web of algebraic constraints, in view of the algebraic renormalization and of the extension of the non-renormalization theorems holding for N=2 SYM theory without matter.Comment: 28 pages, final version to be published on CQ
