Corrigendum to “Some problems of Wielandt revisited” [J. Algebra 302 (1) (2006) 167–185]

An error in the proof of Theorem 2 in [W. Knapp, Some problems of Wielandt revisited, J. Algebra 302 (1) (2006) 167–185] (concerning the action of semisimple groups) is corrected.     

Corrigendum to “Colorings and spectral radius of digraphs” [Discrete Math. 339 (1) (2016) 327–332]

Two errors in the original article are corrected so as to validate the major results. Thus, the digraphs that have the minimum and second minimum spectral radius among all strongly connected digraphs with given order and dichromatic number are determined.     

Corrigendum to “(p,1)-total labelling of graphs” [Discrete Math. 308 (2008) 496–513]

We give a corrected proof of Proposition 51 of the paper cited in the title.     

Corrigendum to “Heavy-Traffic Asymptotics for Stationary GI/G/1-Type Markov Chains” [Oper. Res. Lett. 40 (2012) 185–189]

This corrigendum provides corrections for several errors in the previously published letter “Heavy-Traffic Asymptotics for Stationary GI/G/1-Type Markov Chains” [Operations Research Letters 40 (2012) 185–189].     

Corrigendum to “Property (gb) and perturbations” [J. Math. Anal. Appl. 383 (1) (2011) 82–94]

We give a complete reference for work cited in [M.H.M. Rashid, Property (gb) and perturbations, J. Math. Anal. Appl. 383 (1) (2011) 82–94].     

Corrigendum to “Genus fields of abelian extensions of rational congruence function fields” [Finite Fields Appl. 20 (2013) 40–54]

There is an error in the proof of Theorem 4.2 of the paper. Here we correct the error and give the right statements for Theorems 4.2, 4.5 and 5.2.
