The Orbifolds of Permutation-Type as Physical String Systems at Multiples of V. Cyclic Permutation Orbifolds
M. B. Halpern
I consider the prime free-bosonic permutation orbifolds as interacting physical string systems at . As a first step, I introduce twisted tree dia…
The Orbifolds of Permutation-Type as Physical String Systems at Multiples of III. The Spectra of Strings
M. B. Halpern
In the second paper of this series, I obtained the twisted BRST systems and extended physical-state conditions of all twisted open and closed strings. In this paper,…
The Orbifolds of Permutation-Type as Physical String Systems at Multiples of c=26 II. The Twisted BRST Systems of \hatc=52 Matter
M. B. Halpern
This is the second in a series of papers which consider the orbifolds of permutation-type as candidates for new physical string systems at higher central charge. In the first paper…
Conformal Field Theories: From Old to New
Jan de Boer, M. B. Halpern
In a short review of recent work, we discuss the general problem of constructing the actions of new conformal field theories from old conformal field theories. Such a construction…
The Generic World-Sheet Action of Irrational Conformal Field Theory
K. Clubok, M. B. Halpern
We review developments in the world-sheet action formulation of the generic irrational conformal field theory, including the non-linear and the linearized forms of the action. Thes…
