Linear Codes - Mathematical and Statistical Sciences
parity-check matrix H has minimum distance (exactly) d if and only if every set of d-1 columns of H are linearly independent, and some set of d columns are linearly dependent. Hence this theorem could be used to determine the minimum distance of a …

Proof Methods - Mathematical and Statistical Sciences
www-math.ucdenver.eduWriting mathematical proofs is therefore an art form (the art of convincing) and a social process since it is directed at people (the readers). A mathematical proof of a statement strongly depends on who the proof is written for. Proofs for a research audience are quite different from those found in textbooks. And even textbook proofs look ...
