Homotopy Transfer Theorem for Linearly Compatible Di-algebras
  This paper studies the operad of linearly compatible di-algebras, denoted by $As^{2}$, which is a nonsymmetric operad encoding the algebras with two binary operations that satisfy individual and sum associativity conditions. We also prove that the operad $As^{2}$ is exactly the Koszul dual operad of the operad $^{2}As$ encoding totally compatible di-algebras. We show that the operads $As^{2}$ and $^{2}As$ are Koszul by rewriting method. We make explicit the Homotopy Transfer Theorem for $As^{2}$-algebras.
