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
- Weighted Complete Intersections
A number of different types of Calabi-Yau theories is
contained in the class
at c=9 (116kb) whose complete construction
in two independent ways has been described in the
- Theories with 5 (scaling) variables comprise the complete
quasismooth Calabi-Yau hypersurfaces embedded in
- The list of
(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.

Calabi-Yau complete intersections in toric varieties.

(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.

ps file (107 kb)
- Supplement listing (0,2) Landau-Ginzburg theories
with gauge groups
- The Hodge numbers for a few fibered fourfolds have been described in the
context of F-Theory and M-theory in the paper
The complete set of codimension one transverse Calabi-Yau fourfolds
has been described in the paper hep-th/9812195,
available as a ps file
Furthermore, a large amount of configurations with codimension 2, 3
and 4 has been computed.
The supplement lists all the data.
