| contents | Under the common theme of splitting of operations, the notions of (tri)dendriform algebras, pre-Lie algebras and post-Lie algebras have attracted sustained attention with broad applications. An important aspect of their studies is as the derived structures of Rota-Baxter operators on associative or Lie algebras. This paper introduces extended versions of (tri)dendriform algebras, pre-Lie algebras, and post-Lie algebras, establishing close relations among these new structures that generalize those among their classical counterparts. These new structures can be derived from the extended Rota-Baxter operator, which combines the standard Rota-Baxter operator and the modified Rota-Baxter operator. To characterize these new notions as the derived structures of extended Rota-Baxter algebras, we define the binary quadratic operad in companion with an operad with nontrivial unary operations. Then the extended (tri)dendriform algebra is shown to be the binary quadratic nonsymmetric operads in companion to the operad of extended Rota-Baxter algebras. As a key ingredient in achieving this and for its own right, the free extended Rota-Baxter algebra is constructed by bracketed words. |
