Calabi-Yau Threefolds
Three classes of Calabi-Yau manifolds have been constructed completely
at this point.
- Complete Intersection Calabi-Yau Manifolds
The class of complete intersection manifolds embedded in
products of ordinary projective spaces, so-called
CICYs
- Weighted Complete Intersections
A number of different types of Calabi-Yau theories is
contained in the class
Landau-Ginzburg theories
at c=9 (116kb) whose complete construction
in two independent ways has been described in the
following
LG references.
- Theories with 5 (scaling) variables comprise the complete
class of
7,555 (78kb)
quasismooth Calabi-Yau hypersurfaces embedded in
weighted 4-space.
- The list of
3,284
(39kb) theories with more than five variables define
higher-dimensional manifolds, so-called
Special Fano Varieties or
Generalized Calabi-Yau Manifolds . A geometric projection
identifies the subsector of the cohomology of these
higher-dimensional varieties which parametrizes the string
spectra described in the list.
- Toric constructions
- Calabi-Yau orbifolds (soon to come, not yet in operation)
Fibered Calabi-Yau threefolds,
of interest for dualities in string theory,
M-theory and F-theory:
Software for Calabi-Yau Threefolds
- TESS , a code which
computes the Hodge number of complete intersection Calabi-Yau manifolds
embedded in products of ordinary projective spaces.
(Provided by T.Hubsch (hubsch@scs.howard.edu))
- INSTANTON ,
a Mathematica program which calculates instanton numbers and other data for
Calabi-Yau complete intersections in toric varieties.
(Provided by A.Klemm (klemm@nxth04.cern.ch))
- PUNTOS is a Maple
program which triangulates polyhedra and computes the various phases
of toric hypersurfaces. A LaTex
manual explains the
program.

(0,2) Calabi-Yau Threefolds and Mirror Symmetry
The construction of a first large class of (0,2) theories
has been discussed in the paper hep-th/9609167.
A supplement lists the (0,2) Landau-Ginzburg theories
with various gauge groups considered in that paper.

Calabi-Yau Fourfolds
- The Hodge numbers for a few fibered fourfolds have been described in the
context of F-Theory and M-theory in the paper
hep-th/9606148.
-
The complete set of codimension one transverse Calabi-Yau fourfolds
has been described in the paper hep-th/9812195,
available as a ps file
(137 kb).
Furthermore, a large amount of configurations with codimension 2, 3
and 4 has been computed.
-
The supplement lists all the data.
