    E. L. Starostin & G. H. M. van der Heijden: The shape of a Möbius strip. Nature Materials 6 (2007): 563-567. DOI: 10.1038/nmat1929. (2007) [Link! 28/06/2012]
    Abstract: "The Möbius strip, obtained by taking a rectangular strip of plastic or paper, twisting one end through 180°, and then joining the ends, is the canonical example of a one-sided surface. Finding its characteristic developable shape has been an open problem ever since its first formulation in refs [1, 2]. Here we use the invariant variational bicomplex formalism to derive the first equilibrium equations for a wide developable strip undergoing large deformations, thereby giving the first non-trivial demonstration of the potential of this approach. We then formulate the boundary-value problem for the Möbius strip and solve it numerically. Solutions for increasing width show the formation of creases bounding nearly flat triangular regions, a feature also familiar from fabric draping [3] and paper crumpling [4, 5]. This could give new insight into energy localization phenomena in unstretchable sheets, which might help to predict points of onset of tearing. It could also aid our understanding of the relationship between geometry and physical properties of nano- and microscopic Möbius strip [7, 8, 9]."

Stölzner: John von Neumann and the Foundations of Quantum Physics (Vienna Circle Yearbook series). Kluwer Academic Press, 2001: pp. 135-152. Abstract: "A brief history of the Stone-von Neumann uniqueness theorem and its ramifications is provided. The influence of this theorem on the development of quantum theory, which was its initial source of motivation, is emphasized. In addition, its impact upon mathematics itself is suggested by considering certain subsequent developments in originally unanticipated directions."
