Let $k$ be a field. A finite dimensional k-algebra is said to be minimal representation-infinite provided it is representation-infinite and all its proper factor algebras are representation-finite. Our aim is to classify the special biserial algebras which are minimal representation-infinite. The second part describes the corresponding module categories.

Keywords: Minimal representation-infinite algebras, special biserial algebras, quiver, Auslander–Reiten quiver, Auslander–Reiten quilt, sectional paths, irreducible maps, Gorenstein algebras, semigroup algebras
