Abstract:

We show that the matrix query language $mathsf{MATLANG}$ corresponds to a natural fragment of the positive relational algebra on $K$-relations. The fragment is defined by introducing a composition operator and restricting $K$-relation arities to two. We then proceed to show that $mathsf{MATLANG}$ can express all matrix queries expressible...More
