WebAbstract We compute the 2-primary Dyer-Lashof operations in the string topology of several families of manifolds, specifically spheres and a variety of projective spaces. These operations, while well known in the context of iterated loop spaces, give a collection of homotopy invariants of manifolds new to string topology. WebThe Dyer-Lashof algebra The Dyer-Lashof operations We consider the case when A = H is the Eilenberg-MacLane spectrum. Recall that D 2S mis homotopy equivalent to RP1 m. Let e r 2H r+2m(D 2Sm) be the generator in degree r + 2m. De ne the Dyer-Lashof operations Qr;r 2Z to be Qr(x) = e r m x for x in degree m. From the de nition, we have …

WebX is endowed with further structure: the Dyer-Lashof and Browder operations, originally introduced in the study of iterated loop spaces. To use the notation of [CLM76], there are unary operations Q 0, Q 1 and a binary operation λ 1. The zeroth Dyer-Lashof operation Q 0 is just the pth power map with respect to the product. The Browder operation λ Webthe algebra of (Araki–Kudo–)Dyer–Lashof operations or simply the Dyer–Lashof al-gebra. In terms of stable homotopy theory, we may identify En(X) with the homotopy group ˇ +n of the function spectrum F(1X;E) = EX. From this point of view, these groups have stable operations because F(1 + X;E) is a left module over the endomorphism ... birth certificate status telangana ghmc

Webproperties of the Dyer-Lashof operations in §2. These operations have been calculated in the homology of all these spaces, and the dual operations have also been computed. As applications one can cal culate the indecomposable elements of the homology of these spaces over the Dyer-Lashof algebra R and the AR-Hopf algebra maps be WebDyer-Lashof operations and Hopkins-Mahowald’s theorem that there is an equivalence of E 2-ring spectra HF p’M(W2S3!BGL 1(S^)). Note that Bökstedt’s theorem reduces to the following fact: Claim 0.1. THH(F p)=HF p S¥+WS3. Then THH (F p) = p (THH(F p)) is the homology of WS3 with F p coefficients, which has a single generator in degree 2.
