On Bass’ Question for Finitely Generated Algebras over Large Fields
Abstract. Recently Cortiñas-Haesemayer-Walker-Weibel gave affirmative answer to Bass’ 1972 question on NK-groups for algebras of essentially finite type over large fields of characteristic 0. Here we give an alternative short proof of this result for algebras of finite type over such fields. Our approach is based on classical techniques in higher K-theory of rings and a direct Ki-analogue of an...
متن کاملRelatively hyperbolic groups, rapid decay algebras and a generalization of the Bass conjecture
By deploying dense subalgebras of `.G/ we generalize the Bass conjecture in terms of Connes’ cyclic homology theory. In particular, we propose a stronger version of the `-Bass Conjecture. We prove that hyperbolic groups relative to finitely many subgroups, each of which posses the polynomial conjugacy bound property and nilpotent periodicity property, satisfy the `-Stronger-Bass Conjecture. Mor...
متن کاملThe bass and topological stable ranks for algebras of almost periodic functions on the real line
Let Λ be a sub-semigroup of the reals. We show that the Bass and topological stable ranks of the algebras APΛ = {f ∈ AP : σ(f) ⊆ Λ} of almost periodic functions on the real line and with Bohr spectrum in Λ are infinite whenever the algebraic dimension of the Q-vector space generated by Λ is infinite. This extends Suárez’s result for APR = AP. Also considered are general subalgebras of AP. Intro...
متن کاملRelatively Hyperbolic Groups, Rapid Decay Algebras and a Generalization of the Bass Conjecture
By deploying dense subalgebras of ℓ 1 (G) we generalize the Bass conjecture in terms of Connes' cyclic homology theory. In particular, we propose a stronger version of the ℓ 1-Bass Conjecture. We prove that hyperbolic groups relative to finitely many subgroups, each of which posses the polynomial conjugacy-bound property and nilpotent periodicity property, satisfy the ℓ 1-Stronger-Bass Conjectu...
متن کاملHierarchical Bass model
We propose a new model about diffusion of a product which includes a memory of how many adopters or advertisements a non-adopter met, where (non-)adopters mean people (not) possessing the product. This effect is lacking in the Bass model. As an application, we utilize the model to fit the iPod sales data, and so the better agreement is obtained than the Bass model.
