About the logo

The logo was inspired (a posteriori, perhaps?) by a T-fold, a nongeometric string background whose simplest example is perhaps where the circles at 0 and at 1 are identified by a T-duality transformation which is an automorphism of the underlying conformal field theory. This very background was the subject of a recent EMPG preprint: EMPG-06-04 and a related background seemed to insinuate itself in EMPG-07-11, during the study of the deformations of the Killing superalgebra of the Kałuża–Klein monopole.

The logo itself (sans the letters) was defined using Mathematica and the (version 6) notebook is available, also as a PDF.
