The Minkowski Norm is, in fact, a norm: https://en.wikipedia.org/wiki/Minkowski_norm https://en.wikipedia.org/wiki/Minkowski_norm // It also has nothing to do with the complex numbers // The author of the linked article said that what he was describing was a norm because it satisfied the triangle inequality (among other things). I'm just pointing out that the (among other things) was enough for it to be a norm. I certainly wished somebody had pointed out to me that not all norms need to satisfy the triangle property. There have been spaces where I wasted months of effort trying to find a norm which satisfied the triangle inequality, when a more minkowski-like norm would have been perfectly adequate.
