Web6 de mar. de 2024 · And if a non-commutative finite ring with 1 has the order of a prime cubed, then the ring is isomorphic to the upper triangular 2 × 2 matrix ring over the Galois field of the prime. The study of rings of order the cube of a prime was further developed in (Raghavendran 1969) and (Gilmer Mott). WebThe results establish the sufficiency of finite field alphabets for linear network coding for asymptotically linearly solvable over some finite field, and proves that certain rings can yield higher linear capacities for certain networks than can a given field.
