E10 Orbifolds
Jeffrey Brown, Surya Ganguli, Ori J. Ganor +1
We study Z2 orbifolds of M-theory in terms of E10. We find a simple relation between the Z2 action on E10 and the imaginary root that corresponds [hep-th/0401053] to the "twisted s…
The General Twisted Open WZW String
M. B. Halpern, C. Helfgott
We recently studied two large but disjoint classes of twisted open WZW strings: the open-string sectors of the WZW orientation orbifolds and the so-called basic class of twisted op…
A Basic Class of Twisted Open WZW Strings
M. B. Halpern, C. Helfgott
Recently, Giusto and Halpern reported the open-string description of a certain basic class of untwisted open WZW strings, including their associated non-commutative geometry and op…
M-theory and E10: Billiards, Branes, and Imaginary Roots
Jeffrey Brown, Ori J. Ganor, Craig Helfgott
Eleven dimensional supergravity compactified on admits classical solutions describing what is known as billiard cosmology - a dynamics expressible as an abstract (billiard…
