The authors study the relation between the norm of a projection onto a subspace and the norm of the projection onto the complementary subspace, assuming that one of them is finite-codimensional. The results are nice, and the problem is related in some way to the problem of minimal projections. The authors, unfortunately, fail to refer to the work of Franchetti and Cheney, and to the work of Lewicky on minimal projection.
