On the minimal number of critical points of smooth maps between closed manifolds
New additional information concerning the minimal number of critical points of smooth proper mappings between closed connected surfaces (possibly with boundary) without critical points on the boundary is presented [see \textit{D. Andrica} and \textit{L. Funar}, J. Lond. Math. Soc., II. Ser. 69, No. 3, 783--800 (2004); addendum ibid. 73, No. 1, 231--236 (2006; Zbl 1052.57051); \textit{L. Funar, C. Pintea} and \textit{P. Zhang}, Proc. Am. Math. Soc. 138, No. 1, 355--365 (2010; Zbl 1192.57014)].
