An Introduction to Predictive Processing Models of Perception and Decision‐Making

open access: yesTopics in Cognitive Science, EarlyView., 2023
Abstract The predictive processing framework includes a broad set of ideas, which might be articulated and developed in a variety of ways, concerning how the brain may leverage predictive models when implementing perception, cognition, decision‐making, and motor control.

Maximal left ideals of the Banach algebra of bounded operators on a Banach space [PDF]

open access: yes, 2013
We address the following two questions regarding the maximal left ideals of the Banach algebra $\mathscr{B}(E)$ of bounded operators acting on an infinite-dimensional Banach pace $E$: (Q1) Does $\mathscr{B}(E)$ always contain a maximal left ideal which

Differential operators and Cherednik algebras [PDF]

open access: yes, 2007
We establish a link between two geometric approaches to the representation theory of rational Cherednik algebras of type A: one based on a noncommutative Proj construction, used in [GS]; the other involving quantum hamiltonian reduction of an algebra of ...

Reflexivity of the translation-dilation algebras on L^2(R)

open access: yes, 2003
The hyperbolic algebra A_h, studied recently by Katavolos and Power, is the weak star closed operator algebra on L^2(R) generated by H^\infty(R), as multiplication operators, and by the dilation operators V_t, t \geq 0, given by V_t f(x) = e^{t/2} f(e^t ...

A note on rank-one operators in reflexive algebras [PDF]

open access: yesProceedings of the American Mathematical Society, 1983
It is shown that if the invariant subspace lattice of a reflexive algebra A \mathcal {A} , acting on a separable Hilbert space, is both commutative and completely distributive, then the algebra generated by the rank-one operators of A \mathcal {A} is dense in A \mathcal

Some Results on Fixed Point Theorems in Banach Algebras

open access: yesInternational Journal of Analysis and Applications, 2017
Let X be a Banach algebra and D be a nonempty subset of X. Let (T 1, T 2) be a pair of self mappings on D satisfying some specific conditions. Here we discuss different situations for existence of solution of the operator equation u = T 1 uT 2 u in D ...

Tensor products of subspace lattices and rank one density

open access: yes, 2012
We show that, if $M$ is a subspace lattice with the property that the rank one subspace of its operator algebra is weak* dense, $L$ is a commutative subspace lattice and $P$ is the lattice of all projections on a separable infinite dimensional Hilbert ...

Operator algebras from the discrete Heisenberg semigroup

open access: yes, 2010
We study reflexivity and structure properties of operator algebras generated by representations of the discrete Heisenberg semi-group. We show that the left regular representation of this semi-group gives rise to a semi-simple reflexive algebra.
