Using the theory of involutive Heegaard Floer knot theory developed byHendricks-Manolescu, we define two involutive analogs of the Upsilon knotconcordance invariant of Ozsvath-Stipsicz-Szabo. These involutive invariantsare piecewise linear functions defined on the interval [0,2]. Each is aconcordance invariant and provides bounds on the three-genus of a knot.
