Webbased searchable databases

A printable list of the terminal Fano polytopes in three dimensions is available in pdf format, in ps format, and as plain text. The C source code for generating the list is available here.

Tables of the lowindex LDPpolygons are here. Plain text copies of the raw data are available here.

Plain text copies of the classification of terminal and canonical weighted projective space in dimension 4 (along with source code) are available here. The web page also contains the classification of all 1point lattice simplices in dimension 4.

Plain text copies of the classification of terminal Gorenstein weighted projective space in dimensions 5 to 10 (along with the source code used to generate them) can be downloaded here.

Magma code to generate the databases of canonical and CalabiYau 3folds can be downloaded here.

Magma code to recreate the classification of lreflexive polygons is available here.

Magma code to calculate classifications of wellformed, quasismooth hypersurfaces in weighted projective space, along with the resulting fourfold classifications are available for download here.

In the press

Math in the Media: A monthly magazine from the AMS
"Beautiful pictures and animations reminiscent of flowers or folding cloth grace recent posts of this blog, in which most entries take the form of a technical conversation between specialists Tom Coates, Alessio Corti, Sergei Galkin, Vasily Golyshev, and Al Kasprzyk..."

Physics World: Nature's building blocks brought to life
"The scientists are looking for shapes, known as "Fano varieties", which are basic building blocks and cannot be broken down into simpler shapes. They find Fano varieties by looking for solutions to a variety of string theory, a theory that seeks to unify quantum mechanics with gravity..."

Science: Elementary mathematics
"An international group of mathematicians hopes to do for math what Dmitri Mendeleev’s periodic table did for chemistry by identifying the shapes in three, four, and five dimensions that cannot be divided into other shapes..."

New Scientist: Atoms ripple in the periodic table of shapes
"This rippling structure may look like a piece of origami, or an intricate scarf. In fact, it is geometry's answer to the atom because it can't be broken down into smaller components. Inspired by string theory, there is now a way to classify these atoms by their properties – and hunt down their higher dimensional cousins..."

Cosmos: Mathematicians propose periodic table of shapes
"Mathematicians have embarked on a threeyear project to create their own version of the periodic table that will provide a vast directory of all the possible shapes in the universe across three, four and five dimensions..."
