We determine the extent to which the collection of Γ-Euler-Satake characteristics classify closed 2-orbifolds. In particular, we show that the closed, connected, effective, orientable 2-orbifolds are classified by the collection of Γ-EulerSatake characteristics corresponding to free or free abelian Γ and are not classified by those corresponding to any finite collection of finitely generated di...
متن کاملArakelov Euler Characteristics
Fröhlich suggested considering invariants of ON together with the trace pairing (x, y) → TrN/Q(xy). This leads to local and global Hermitian discriminants of (ON, Tr) in “Hermitian classgroups.” Cassou-Noguès and Taylor showed these discriminants were enough to determine both local and global symplectic root numbers. This approach will be generalized to projective schemes over Z in lecture 3. O...
متن کاملHandlebody Orbifolds and Schottky Uniformizations of Hyperbolic 2-orbifolds
The retrosection theorem says that any hyperbolic or Riemann surface can be uniformized by a Schottky group. We generalize this theorem to the case of hyperbolic 2-orbifolds by giving necessary and sufficient conditions for a hyperbolic 2-orbifold, in terms of its signature, to admit a uniformization by a Kleinian group which is a finite extension of a Schottky group. Equivalent^, the condition...
متن کاملTwisted Open Strings from Closed Strings: The WZW Orientation Orbifolds
Including world-sheet orientation-reversing automorphisms ĥσ ∈ H− in the orbifold program, we construct the operator algebras and twisted KZ systems of the general WZW orientation orbifold Ag(H−)/H−. We find that the orientation-orbifold sectors corresponding to each ĥσ ∈ H− are twisted open WZW strings, whose properties are quite distinct from conventional open-string orientifold sectors. As s...
متن کاملClosed String Tachyons, Non-Supersymmetric Orbifolds and Generalised McKay Correspondence
We study closed string tachyon condensation on general non-supersymmetric orbifolds of C2. Extending previous analyses on Abelian cases, we present the classification of quotients by discrete finite subgroups of GL(2;C) as well as the generalised Hirzebruch-Jung continued fractions associated with the resolution data. Furthermore, we discuss the intimate connexions with certain generalised vers...
