Octonionic isometric isomorphisms and partial isometry

Qinghai Huo, Guangbin Ren, Zhenghua Xu

Very recently, two new notions of para-linear mappings and weak associative orthonormal bases were introduced in octonionic functional analysis, which have been proved to be powerf…

Octonionic Riesz-Dunford functional calculus

Qinghai Huo, Guangbin Ren, Irene Sabadini +1

The Riesz-Dunford functional calculus over the algebra of octonions, denoted by , has long been an open problem due to the nonassociativity of octonions. Two core obsta…

Structure of octonionic Hilbert spaces with applications in the Parseval equality and Cayley-Dickson algebras

Qinghai Huo, Guangbin Ren

Contrary to the simple structure of the tensor product of the quaternionic Hilbert space, the octonionic situation becomes more involved. It turns out that an octonionic Hilbert sp…

Para-linearity as the nonassociative counterpart of linearity

Qinghai Huo, Guangbin Ren

In an octonionic Hilbert space , the octonionic linearity is taken to fail for the maps induced by the octonionic inner products, and it should be replaced with the octonionic p…
