### Abstract

Let $c_n(A),\ n=1,2,\ldots,$ be thesequence of codimensions of an algebra $A$ over a field $F$ ofcharacteristic zero. We classify the algebras $A$ (up toPI-equivalence) in case this sequence is bounded by a linearfunction. We also show that this property is closely related tothe following: if $l_n(A), \ n=1,2,\ldots,$ denotes the sequenceof colengths of $A$, counting the number of $S_n$-irreduciblesappearing in the $n$-th cocharacter of $A$, then $\lim_{n\to\infty} l_n(A)$ exists and is bounded by $2$.
