A note on a new result related to Chartrand, Kaigars and Lick's theorem (2212.04637v6)

Abstract: In this note, we prove a theorem covering Chartrand, Kaigars, and Lick's theorem in [Proc. Amer. Math. Soc. 32 (1972), 63-68]. As an application, we give a simpler proof of theorem proved by Mader [J. Graph Theory 65 (2010), 61-69. (Theorem 1)].
