On Special Jordan Algebras [PDF]
for a and b in e is called quasimultiplication, and any linear subspace X over 8 of e which is closed with respect to this operation forms a corresponding algebra W. We call an algebra isomorphic to such an algebra a special Jordan algebra and see that special Jordan algebras are commutative but not, in general, associative.

Large‐Amplitude Periodic Solutions to the Steady Euler Equations With Piecewise Constant Vorticity
ABSTRACT We consider steady solutions to the incompressible Euler equations in a two‐dimensional channel with rigid walls. The flow consists of two periodic layers of constant vorticity separated by an unknown interface. Using global bifurcation theory, we rigorously construct curves of solutions that terminate either with stagnation on the interface ...

Independent quantum systems and the associativity of the product of quantum observables
We start from the assumption that the real valued observables of a quantum system form a Jordan algebra which is equipped with a compatible Lie product characterizing infinitesimal symmetries, and ask whether two such systems can be considered as ...

Jordan and Local Multipliers on Certain Banach Algebras are Multipliers [PDF]
We prove that every continuous Jordan multiplier $T$ from a $C^*$-algebra $A$ into a Banach $A$-bimodule $X$ is a multiplier. We also characterize continuous linear maps on $C^*$-algebras and standard operator algebras determined by preserving some ...

Generalized Projective product of semi-rings
The concept of Differential algebra has been played an influential role in various directions of abstract algebra. This notation has been considered before fifty years ago with semi-ring and several types of rings.

Generalized Derivations and Bilocal Jordan Derivations of Nest Algebras
Let H be a complex Hilbert space and B(H) the collection of all linear bounded operators, A is the closed subspace lattice including 0 an H, then A is a nest, accordingly alg A={T∈B(H):TN⊆N, ∀N∈A} is a nest algebra. It will be shown that of nest algebra,

On Mappings That Preserve the Jordan Product: A Revisited Study
We study bijective maps between algebras that preserve Jordan-type products. More precisely, given algebras A and B, we consider maps Θ:A→B satisfying Θ(AB+BA)=Θ(A)Θ(B)+Θ(B)Θ(A) or, more generally, preserving the Jordan triple product Θ({A,B,C})={Θ(A),Θ ...
