Primary ideal theory for quadratic Jordan algebras

open access: yes, 1973
The notion of a primary ideal was originally introduced in the study of noetherian rings, i.e., commutative associative rings with unity which have the maximum condition on ideals. In more recent years, this notion has been carried over to noncommutative

Continuity of homomorphisms on pro-nilpotent algebras [PDF]

open access: yes, 2011
Let V be a variety of not necessarily associative algebras, and A an inverse limit of nilpotent algebras Ai ∈ V, such that some finitely generated subalgebra S ⊆ A is dense in A under the inverse limit of the discrete topologies on the Ai.

Resonance‐induced restoration of rock permeability degraded by heavy components of crude oil

open access: yesDeep Underground Science and Engineering, EarlyView.
Resonance‐induced changes occur in filtration properties of sedimentary rocks in crude paraffin oil flow under acoustic vibrations. Experimental data on (a) pressure drop; (b) permeability; (c) pressure at the rock inlet; and (d) pressure at the rock outlet are presented.

An Efficient Quasi‐Static Condensation‐Based Framework for Seismic Analysis of Multi‐Supported Secondary Structures

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Multi‐supported non‐structural components (NSCs) are prone to seismic damage, yet their response prediction remains challenging when support motions are spatially incoherent. This study proposes an enhanced quasi‐static condensation (EQSC) method for linear, lightweight, dynamically detuned multi‐supported NSCs under the neglect of primary ...

Edge‐Based Discretizations on Triangulations in Any Dimension, With Special Attention to Four‐Dimensional Space

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
This article provides important geometric formulas for node‐centered, edge‐based schemes in any number of dimensions. These formulas are noteworthy, as they do not require the explicit formation of dual regions. We prove several key geometric results, with a particular focus on the four‐dimensional case, due to potential space‐time applications ...

Coordinate systems and associative algebras

open access: yes, 2015
textThis dissertation applies and extends the techniques of formal algebraic geometry in the setting of certain "smooth" associative algebras and their globalizations, noncommutative manifolds, roughly ringed spaces locally modeled on the free ...
