Student learning of basis, span and linear independence in linear algebra

open access: closedInternational Journal of Mathematical Education in Science and Technology, 2010
One of the earlier, more challenging concepts in linear algebra at university is that of basis. Students are often taught procedurally how to find a basis for a subspace using matrix manipulation, but may struggle with understanding the construct of basis, making further progress harder.

Extension theorems for linear lattices with positive algebraic basis

open access: closedPeriodica Mathematica Hungarica, 1975
An ordered linear spaceV with positive wedgeK is said to satisfy extension property (E1) if for every subspaceL0 ofV such thatL0 ∩K is reproducing inL0, and every monotone linear functionalf0 defined onL0,f0 has a monotone linear extension to all ofV.

A Linear Basis of the Free Akivis Algebra

open access: closedJournal of Mathematical Sciences, 2019
Akivis algebras were introduced in 1976, by \textit{M. A. Akivis} in the paper [Sib. Math. J. 17, 3--8 (1976; Zbl 0337.53018); translation from Sibir. Mat. Zh. 17, 5--11 (1976)]. Let \(F(X)\) be the free nonassociative algebra over a field \(K\) with the set \(X\) of free generators.
