Recently, Kanas and Wiśniowska [7, 8, 9] introduced
the class of $k$-uniformly convex, and related class of $k$-starlike
functions ($0 \le k \infty$), denoted $\ku$ and $\ks$, respectively.
In the present paper a notion of generalized convexity, by applying
the well known Ruscheweyh derivative, is introduced. Some extremal problems
for functions satisfying the condition of generalized convexity are solved.
