We construct the thermodynamic limit of the critical (massless) φ 4 model in 4 dimensions with an ultraviolet cutoff by means of a "partly renormalized" phase space expansion. This expansion requires in a natural way the introduction of effective or "running" constants, and the infrared asymptotic freedom of the model, i.e. the decay of the running coupling… (More)

The Renormalization Group is the name given to a technique for analyzing the qualitative behaviour of a class of physical systems by iterating a map on the vector space of interactions for the class. In a typical non-rigorous application of this technique one assumes, based on one's physical intuition, that only a certain finite dimensional subspace… (More)

Let A(a 1 , · · · , a n) be the finite dimensional, complex Grassmann algebra freely generated by a 1 , · · · , a n. Let M r =

This survey introduces a class of infinite genus Riemann surfaces, specified by means of a number of geometric axioms, to which the classical theory of compact Riemann surfaces up to and including the Torelli Theorem extends. The axioms are flexible enough to include a number of interesting examples, such as the heat curve. We discuss this example and its… (More)

We consider Schrödinger operators with periodic magnetic field having zero flux through a fundamental cell of the period lattice. We show that, for a generic small magnetic field and a generic small Fermi energy, the corresponding Fermi surface is convex and not invariant under inversion in any point.

Tap water scald burns account for 7% to 17% of all childhood scald burns that require hospitalization. Often the burns are severe and disabling. Toddlers and preschool children are the most frequent victims. In 45% of the injuries, the unsupervised victim or peer turned on the tap water; in 28% the cause was abuse. Eighty percent of the homes tested had… (More)

The general restrictions on all economic primitives (i.e., (a) endowments, (b) preferences, and (c) asset return distributions) that yield the CAPM under the expected utility paradigm are provided. These results are then used to derive the class of restrictions on preferences and the distribution of asset returns alone that provides the CAPM. We also show… (More)

Neurodegenerative disorders of sufficient severity to be lethal are also likely to generate psychiatric symptomatology. At times, behavioral changes may predate neurologic manifestations, whereas at other times disturbances in mental status and physical functioning may coexist. In either situation, accurate assessment and appropriate treatment may prove… (More)
