Linking first occurrence polynomials over 𝔽p by Steenrod operations

This paper provides analogues of the results of [G.Walker and R.M.W. Wood, Linking first occurrence polynomials over $F_{2}$ by Steenrod operations, J. Algebra 246 (2001), 739–760] for odd primes $p$ . It is proved that for certain irreducible representations $L (λ)$ of the full matrix semigroup $M_{n} (F_{p})$ , the first occurrence of $L (λ)$ as a composition factor in the polynomial algebra $P = F_{p} [x_{1}, \dots, x_{n}]$ is linked by a Steenrod operation to the first occurrence of $L (λ)$ as a submodule in $P$ . This operation is given explicitly as the image of an admissible monomial in the Steenrod algebra $A_{p}$ under the canonical anti-automorphism $χ$ . The first occurrences of both kinds are also linked to higher degree occurrences of $L (λ)$ by elements of the Milnor basis of $A_{p}$ .
