SUMMARY
The discussion centers on calculating the 2-norm of a 2-dimensional vector in R², specifically for the case where the 2-norm equals 1. The equation that must be satisfied by the vector (x, y) is given by √(x² + y²) = 1, which represents a circle of radius 1 centered at the origin. Additionally, the discussion touches on the unity norm (1-norm) and infinity norm, emphasizing the need to sketch the root loci for these norms in a 2-dimensional space.
