Note on Beta Elements in Homotopy, and an Application to the Prime Three Case
نویسنده
چکیده
Let S0 (p) denote the sphere spectrum localized at an odd prime p. Then we have the first beta element β1 ∈ π2p2−2p−2(S (p)), whose cofiber we denote by W . We also consider a generalized Smith-Toda spectrum Vr characterized by BP∗(Vr) = BP∗/(p, vr 1). In this note, we show that an element of π∗(Vr ∧W ) gives rise to a beta element of homotopy groups of spheres. As an application, we show the existence of β9t+3 at the prime three to complete a conjecture of Ravenel’s: βs ∈ π16s−6(S (3)) exists if and only if s is not congruent to 4, 7 or 8 mod 9.

A new family in the stable homotopy groups of spheres
Let $p$ be a prime number greater than three. In this paper, we prove the existence of a new family of homotopy elements in the stable homotopy groups of spheres $pi_{ast}(S)$ which is represented by $h_nh_mtilde{beta}_{s+2}in {rm Ext}_A^{s+4, q[p^n+p^m+(s+2)p+(s+1)]+s}(mathbb{Z}_p,mathbb{Z}_p)$ up to nonzero scalar in the Adams spectral sequence, where $ngeq m+2>5$, $0leq sExt}_A^{s+2,q[(s+2)p...
متن کاملConcerning the frame of minimal prime ideals of pointfree function rings
Let $L$ be a completely regular frame and $mathcal{R}L$ be the ring of continuous real-valued functions on $L$. We study the frame $mathfrak{O}(Min(mathcal{R}L))$ of minimal prime ideals of $mathcal{R}L$ in relation to $beta L$. For $Iinbeta L$, denote by $textit{textbf{O}}^I$ the ideal ${alphainmathcal{R}Lmidcozalphain I}$ of $mathcal{R}L$. We show that sending $I$ to the set of minimal prime ...
متن کاملOn generalized left (alpha, beta)-derivations in rings
Let $R$ be a 2-torsion free ring and $U$ be a square closed Lie ideal of $R$. Suppose that $alpha, beta$ are automorphisms of $R$. An additive mapping $delta: R longrightarrow R$ is said to be a Jordan left $(alpha,beta)$-derivation of $R$ if $delta(x^2)=alpha(x)delta(x)+beta(x)delta(x)$ holds for all $xin R$. In this paper it is established that if $R$ admits an additive mapping $G : Rlongrigh...

متن کاملTHE BETA ELEMENTS βtp2/r IN THE HOMOTOPY OF SPHERES
In [1], Miller, Ravenel and Wilson defined generalized beta elements in the E2-term of the Adams-Novikov spectral sequence converging to the stable homotopy groups of spheres, and in [5], Oka showed that the beta elements of the form βtp2/r for positive integers t and r survives to the stable homotopy groups at a prime p > 3, when r ≤ 2p − 2 and r ≤ 2p if t > 1. In this paper, we expand the con...
