چکیده
In this note we correct two oversights in Çanakçi et al. (2019) [6] which only occur when a band complex is involved. As consequence see that the mapping cone of morphism between complexes can decompose into arbitrarily many indecomposable direct summands.

On dimensions of derived algebra and central factor of a Lie algebra
Some Lie algebra analogues of Schur's theorem and its converses are presented. As a result, it is shown that for a capable Lie algebra L we always have dim L=Z(L) 2(dim(L2))2. We also give give some examples sup- porting our results.
متن کاملA brief introduction to quaternion matrices and linear algebra and on bounded groups of quaternion matrices
The division algebra of real quaternions, as the only noncommutative normed division real algebra up to isomorphism of normed algebras, is of great importance. In this note, first we present a brief introduction to quaternion matrices and quaternion linear algebra. This, among other things, will help us present the counterpart of a theorem of Herman Auerbach in the setting of quaternions. More ...
متن کاملA Bound for the Nilpotency Class of a Lie Algebra
In the present paper, we prove that if L is a nilpotent Lie algebra whose proper subalge- bras are all nilpotent of class at most n, then the class of L is at most bnd=(d 1)c, where b c denotes the integral part and d is the minimal number of generators of L.
متن کاملCoalgebra-to-Algebra Morphisms
Given a coalgebra p for HG, an algebra s for GH and the obvious notion of morphism from coalgebra to algebra, we observe that morphisms from Gp to s correspond to morphisms from p to Hs in the manner of an adjunction even when there is no adjunction between G and H. This appears to be one of the basic phenomena underlying the transport of special algebras. A proof of Freyd’s Iterated Square The...
متن کاملAlgebra in a Category
In the topos Sets we build algebraic structures out of sets and operations (morphisms between sets) where the operations are required to satisfy various axioms. Once we have translated these axioms into a diagrammatic form, we can copy the definition into any category with finite products. The advantage of such constructions is that many of the complicated concepts turn out to be simple objects...
