Let X R n + m be a matrix with non-negative entries, and p, r

Question:

Let X ∈ Rn+be a matrix with non-negative entries, and p, r ∈  [1, + ∞], with p ≥ r. We consider the problem


1. Show that the function f: Rm→ R, with values

is concave when p ≥ r.

2. Use the previous result to formulate an efficiently solvable convex problem that has Φp,r(X)as optimal value.
