Erratum to: “On n-term approximations with respect to frames bounded in L p (0, 1), 2 < p < ∞”

Erratum to: “Subnormal, permutable, and embedded subgroups in finite groups”

The original version of the article was published in Central European Journal of Mathematics, 2011, 9(4), 915–921, DOI: 10.2478/s11533-011-0029-8. Unfortunately, the original version of this article contains a mistake: Lemma 2.1 (2) is not true. We correct Lemma 2.2 (2) and Theorem 1.1 in our paper where this lemma was used.     

Erratum to: “Smooth metric measure spaces, quasi-Einstein metrics, and tractors”

The original version of the article was published in Central European Journal of Mathematics, 2012, 10(5), 1733–1762, DOI: 10.2478/s11533-012-0091-x. Unfortunately, it contains a typographical error in display of (27). Here we display the correct version of the equations.     

Corrigendum to “Semiring and semimodule issues in MV-algebras,Communications in Algebra 41:3 (2013), 1017–1048”

With the present note the authors intend to correct a mistake in the paper Semiring and semimodule issues in MV-algebras, Communications in Algebra 41:3 (2013), 1017–1048, by the same authors.     

Erratum to “On α-DICC modules” Commun. Algebra. 22(6):1933–1944 (1994)

We give a correct statement for [2 Karamzadeh, O. A. S., Motamedi, M. (1994). On α-DICC modules. Commun. Algebra 22(6):1933–1944.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar], Proposition 1.2]. However, this new form of the proposition needs no different proof from that of [2 Karamzadeh, O. A. S., Motamedi, M. (1994). On α-DICC modules. Commun. Algebra 22(6):1933–1944.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar], Proposition 1.2].     

Addendum to “Progress in celestial mechanics” [RCD, 2012, vol. 17, no. 1, pp. 6–23]

We use this addendum to indicate a remarkable and simple generalization of a classical property of two-body motions.     

Erratum to: “Integral Theory for Hopf Algebroids” [Algebra Represent. Theory (2005) 8:563–599]

Because of similar errors in Lemma 2.6 and Theorem 4.2, we need to add stronger assumptions in several statements.
