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.
متن کاملf-Orthomorphisms and f-Linear Operators on the Order Dual of an f-Algebra
and Applied Analysis 3 It should be noted that the mapping V : A∼ n → Orth A∼ defined by V F VF for all F ∈ A∼ n, where VF f F · f for every f ∈ A∼, is an algebra and Riesz isomorphism cf. 2, Proposition 2.2 . Theorem 2.1. For 0 ≤ f ∈ A∼, Tf is an interval preserving lattice homomorphism. Proof. Clearly, Tf is linear and positive. Since the mapping V is a lattice homomorphism and VF, VG ∈ Orth ...
متن کاملSolving fractional evolution problem in Colombeau algebra by mean generalized fixed point
The present paper is devoted to the existence and uniqueness result of the fractional evolution equation $D^{q}_c u(t)=g(t,u(t))=Au(t)+f(t)$ for the real $qin (0,1)$ with the initial value $u(0)=u_{0}intilde{R}$, where $tilde{R}$ is the set of all generalized real numbers and $A$ is an operator defined from $mathcal G$ into itself. Here the Caputo fractional derivative $D^{q}_c$ is used i...

متن کاملGlobal structure of the mod two symmetric algebra , H ∗ ( BO ; F 2 ) , over the Steenrod Algebra
The algebra S of symmetric invariants over the field with two elements is an unstable algebra over the Steenrod algebra A, and is isomorphic to the mod two cohomology of BO , the classifying space for vector bundles. We provide a minimal presentation for S in the category of unstable A-algebras, i.e., minimal generators and minimal relations. From this we produce minimal presentations for vario...
