On an approximate automorphism on a $C^{*}$-algebra

On subalgebras of an evolution algebra of a "chicken" population

We consider an evolution algebra which corresponds to a bisexual population with a set of females partitioned into finitely many different types and the males having only one type. For such algebras in terms of its structure constants we calculate right and plenary periods of generator elements. Some results on subalgebras of EACP and ideals on low-dimensional EACP are obtained.

More on the anti-automorphism of the Steenrod algebra

has a topological interpretation too: If K is a finite complex then the homology of the Spanier-Whitehead dual DK+ of K+ is canonically isomorphic to the cohomology of K . Under this isomorphism the left action by θ ∈ A on H∗(K) corresponds to the right action of χθ ∈ A on H∗(DK+). In 1974 Davis [3] proved that sometimes much more efficient ways exist to compute χSqn ; for example (3) χSq2 r−1 ...
