Octonion Polynomials with Values in a Subalgebra
[OWP-2020-21] (Mathematisches Forschungsinstitut Oberwolfach, 2020-10-22)In this paper, we prove that given an octonion algebra A over a field F, a subring E⊆F and an octonion E-algebra R inside A, the set S of polynomials f(x)∈A[x] satisfying f(R)⊆R ...
