In this paper, we prove that every matrix over a division ring is representable as a product of at most 10 traceless matrices as well as a product of at most four semi-traceless matrices. By applying this result and the obtained so far other results, we show that elements of some algebras possess some rather interesting and nontrivial decompositions into products of images of non-commutative polynomials.
We make some attempts to define a general notion of groups and fields of dimension one, and to determine their algebraic properties.
We address the question of point particle motion coupled to classical fields, in the context of scalar fields derived from higher-order Lagrangians and BLTP electrodynamics.
