Cyclic quotient singularities and continued fractions

Cyclic quotient singularities form the first non-trivial class of singular toric varities. Combinatorially they arise from two- dimensional cones. These cones are deeply connected with continued fractions. This allows one to reinterpret the algebraic geometry of cyclic quotient singularities first combinatorially via the cones and then in terms of the continued fractions.

After introducing this connection and the involved objects, I will present examples illustrating a combinatorial interpretation of certain derived functors from algebraic geometry in terms of continued fractions.
