It is shown that associative algebras equipped with a Rota-Baxter operator of arbitrary weight always give such dendriform structures.13 pages, no figures, short remark at the end of Sect. 4 added, minor typos correctedMathematical PhysicsHigh Energy Physics - TheoryQuantum Algebra16B99;81T15;81T18;17B81text
