Simple homotopy theory for Fukaya categories

open access: yesJournal of Topology, Volume 19, Issue 3, September 2026.
Abstract We develop a categorical framework for simple homotopy theory in Fukaya categories, based on the fundamental group of the ambient symplectic manifold. When the first Chern class vanishes, we show that any isomorphism in the Fukaya category of a Weinstein manifold has trivial Whitehead torsion.

Ways of linking geometry and algebra, the case of Geogebra

open access: yes, 2007
This paper discusses ways of enhancing the teaching of mathematics through enabling learners to gain stronger links between geometry and algebra. The vehicle for this is consideration of the affordances of GeoGebra, a form of freely-available open-source

Progress in Commutative Algebra 2

open access: yes, 2012
This is the second of two volumes of a state-of-the-art survey article collection which originates from three commutative algebra sessions at the 2009 Fall Southeastern American Mathematical Society Meeting at Florida Atlantic University.

Topics in orbifold geometry and Gorenstein homogeneous spaces [PDF]

open access: yes
I study two problems from different domains. The first problem is related to orbifold geometry and the second to Gorenstein homogeneous spaces. Though two different topics, they share a common theme: the Gorenstein property.

Hidden constructions in abstract algebra: Krull dimension of distributive lattices and commutative rings

open access: yes, 2003
We present constructive versions of Krull's dimension theory for commutative rings and distributive lattices. The foundations of these constructive versions are due to Joyal, Espanol and the authors.

Laws of commutativity, associativity, and distributivity: from the fundamental principles of algebra to the methodological tools of a future mathematics teacher

THE TIDINGS of the Baltic State Fishing Fleet Academy Psychological and pedagogical sciences (Theory and methods of professional education)
The article is devoted to a detailed study of three fundamental algebraic laws – commutativity, associativity, and distributivity – in the context of training a mathematics teacher. It is emphasized that the depth of understanding of these laws determines the teacher's ability to foster genuine algebraic thinking in students. Through an analysis of the
