We compute K-theory invariants of algebras of pseudodifferential operators on manifolds with corners and prove an equivariant index theorem for operators invariant with respect to an action of R. We discuss the relation between our results and the η-invariant.

I briefly review the arguments why the braneworld models with infinitevolume extra dimensions could solve the cosmological constant problem, evading Weinberg’s no-go theorem. Then I discuss in detail the established properties of these models, as well as the features which should be studied further in order to conclude whether these models can truly solve the problem. This article is dedicated ...

The Temperley-Lieb algebra T n with parameter 2 is the associative algebra

Infant faces are very salient stimuli. The Kindchenschema describes specific features that characterize a cute infant face. In this study we used a visual adaptation paradigm to investigate the universality of the perceptual properties of the Kindchenschema. In Experiment 1, twenty-four participants adapted to cute and less cute human infant faces and in Experiment 2, twenty-four new participan...

In [Wu], the noncommutative Atiyah-Patodi-Singer index theorem was proved. In this paper, we extend this theorem to the equivariant case.

We present results from a survey for fast pulsars at the Arecibo Observatory. Approximately 260 square degrees of sky were searched, primarily at Galactic latitude jbj < 8. Signals were sampled at intervals of 517 s, allowing for the possibility of detecting pulsars with periods as short as 1 ms or less. Sensitivity varied as a function of sky position. In a typical direction, long period pulsa...

Currently, in Brazil, 1.78% of the population area blood donors, a level lower than the ideal one that, according to WHO, should be between 3% and 5% of the population. Following this scenario, the current study has a general goal of identifying and analyzing the main critical factors of the process of blood donation in the city of Belo Horizonte, MG, under the perception of donors, potential d...

This twenty-four page pamphlet will be of interest and use to all professional workers concerned with the many problems of delinquency. It is clearly written, logically presented, and based on 123

We present a “reasonable” statement about Lie algebras that is equivalent to the Four Color Theorem.
