Unstable splittings related to Brown-Peterson cohomology
We give a new and relatively easy proof of the splitting theorem of the second author for the spaces in the Omega spectrum for BP . We then give the first published proofs of our similar theorems for the spectra P (n).
متن کاملWorking Memory Assessment : Construct Validity of the Brown - Peterson Test
The classical Brown-Peterson task is generally supposed to assess working memory capacities. To date, however, the construct validity of the task remains mostly unexamined. In this context, the aim of the present study was to demonstrate the convergent and the divergent validity as well as the clinical and the developmental sensitivity of a computerized version of the Brown-Peterson test. A gro...
متن کاملA lower bound for coherences on the Brown–Peterson spectrum
We provide a lower bound for the coherence of the homotopy commutativity of the Brown–Peterson spectrum, BP , at a given prime p and prove that it is at least (2p2 + 2p− 2)–homotopy commutative. We give a proof based on Dyer–Lashof operations that BP cannot be a Thom spectrum associated to n–fold loop maps to BSF for n = 4 at 2 and n = 2p + 4 at odd primes. Other examples where we obtain estima...
متن کاملWorking memory in children assessed by the Brown-Peterson Task.
BACKGROUND the working memory is a cognitive skill that contributes to adequate development of language and to the acquisition of reading and writing. A consistent evaluation of the working memory in pre-school and basic school children demonstrates to be important for the early identification of possible learning impairments. AIM to evaluate the development of working memory along the first ...
متن کاملCommutativity conditions for truncated Brown-Peterson spectra of height 2
An algebraic criterion, in terms of closure under power operations, is determined for the existence and uniqueness of generalized truncated Brown-Peterson spectra of height 2 as E∞-ring spectra. The criterion is checked for an example at the prime 2 derived from the universal elliptic curve equipped with a level Γ1(3) structure. 2000MSC: 55P42, 55P43, 55N22 and 14L05
