In the first half of this dissertation we study certain quotient algebras of preprojective
algebras called no-cycle algebras N. These are studied via one-cycle algebras,
which are introduced here. Results include detailed combinatorial information on
N, and in certain special cases a presentation for N as a quiver with relations.
In the second half we consider deformations of coordinate algebras of
Kleinian singularities. Results include an explicit presentation for the deformations
of a type D singularity.
These two themes are tied together at the end by some mainly speculative
comments about the role the various objects studied have to play in representation
