We present some results supporting the Iwase-Sakai conjecture about coincidence of the topological complexity TC(X) and monoidal topological complexity TC (X). Using these results we provide lower and upper bounds for the topological complexity of the wedgeX∨Y . We use these bounds to give a counterexample to the conjecture asserting that TC(X′) ≤ TC(X) for any covering map p : X′ → X. Also we discuss a possible reduction of the monoidal topological complexity to the Lusternik-Schnirelmann category.
