The Differences Between Birkhoff and Isosceles Orthogonalities in Radon Planes

The notion of orthogonality for vectors in inner product spaces is simple, interesting and fruitful. When moving to normed spaces, we have many possibilities to extend this notion. We consider Birkhoff orthogonality and isosceles orthogonality. Recently the constants which measure the difference bet...
