Solar modules treated with lead carboxylate passed the standard test of photovoltaic reliability and had a high yield.

Let a_1,...,a_44 be the rows of coordinates44.txt. Define P = conv(a_1,...,a_44,-a_1,...,-a_44). The certificate proves that P is a centrally symmetric simplicial 7 ...

Input any finite translation quiver by clicking the canvas, or by using keyboard. Save and load your translation quiver. Import AR quiver from String Applet. Select X and Y, then this computes the ...

Can you chip in? As an independent nonprofit, the Internet Archive is fighting for universal access to quality information. We build and maintain all our own systems, but we don’t charge for access, ...

From the viewpoint of mutation, we will give a brief survey of tilting theory and cluster-tilting theory together with a motivation from cluster algebras. Then we will give an introduction to ...

The group of piecewise projective homeomorphisms of the line provides straightforward torsion-free counterexamples to the so-called von Neumann conjecture. The examples are so simple that many ...

ABSTRACT: In this paper we show how the transformations associated with the reduction to the Smith form of some classes of mul-tivariate polynomial matrices are computed. Using a Maple implementation ...

You probably know that the 2010 Fields Medals have been announced. The thing is, I’ve never succeeded in understanding the slightest thing about it. It’s as if it’s got a hard, shiny shell—it resists ...
