Abstract

We prove the formula \begin{equation*} TC(X\vee Y)=\max\{TC(X),TC(Y),cat(X\times Y)\} \end{equation*} for the topological complexity of the wedge XYX\vee Y.

Comments

There is a mistake in the Proof of Theorem 1.4. The statement "any two of these sets intersect at a single point $w_0=((x_0,y_0),(x_0,y_0))$" is wrong
