Factor categories and infinite direct sums
Following an aproach to the Krull-Schmidt-Azumaya theorem by Harada and Sai we explain how to apply factor categories to understand direct-sum decompositions of serial modules....

GENERALIZED LATTICES OVER ONE-DIMENSIONAL NOETHERIAN DOMAINS
We study direct sum decompositions of pure projective torsion free modules over one-dimensional commutative noetherian domains. Drawing inspiration from the representation theory of orders in separable algebras, we study wh...

The Upper Bound on Antenna Gain and Its Feasibility as a Sum of Characteristic Gains
The upper bound on antenna gain is expressed as a sum of lossy characteristic modes, specifically, as a sum of characteristic far fields squared. The procedure directivity and current-density-based approaches. The upper bou...
