On two occasions I have come upon problems requiring the differences between each point in two matrices or vectors. One such example is to find the extremum points in two arbitrary curves. The solution was seen in the Kronecker product $(\mathbf M=\mathbf A\otimes \mathbf B)$, albeit with a summation rather than a product. I happily called this the Kronecker sum, although I've seen it referred to as the Kronecker product w.r.t. addition.
Now it comes to my attention that my chosen terminology is not only taken, but it has a different meaning. See, for example, Weisstein, Eric W. "Kronecker Sum." From MathWorld--A Wolfram Web Resource. This Kronecker sum is given by $(\mathbf M=\mathbf A\oplus \mathbf B)$.
My question is, does the Kronecker product w.r.t. addition have is own name and symbol?
