Constraints to a justification of commutativity of multiplication

, 2017
In this paper we investigate a pre-service teacher's whole-class discussion at Grade 6, where she attempts to justify the general claim that multiplication is commutative in ℕ. Our analysis points at two conditions that constrain the discussion in class: The first is that the diagram used to represent a multiplicative situation-and the way the diagram ...

Non-commutative optimization problems with differential constraints

New version, more accessible for both physicists and mathematicians, with new results and applications in statistical physics (numerical tests included). If you wonder how far one can go with 2-RDMT or the bootstrap technique, this paper is for you!

Commutative and non-commutative signatures of anisotropic inflation: constraints from planck PR4 data

Physica Scripta
Abstract We present a comparative study of anisotropic inflationary signatures in both commutative and non-commutative spacetime frameworks, using three anisotropic metrics (Models I–III) as inflationary backgrounds. For each model, we consider the primordial scalar power spectrum computed with the in–in formalism,
