Here we study the evolution of cooperation in public-goods games on scale-free networks that are subject to deletion of links connected to the highest-degree individuals, i...

Fibonacci, in 1202 ([8], see also [1], [7]) introduced the greedy algorithm: we take the greatest Egyptian fraction 1 / xx with l/xl < a/b, form the difference a/b-l/xl=:al/bl [where (ax, bx) = 1] and, if allbl is not zero, continue similarly. It is easily seen that the sequence of numerators aQ: = a, al9 a2,... is strictly decreasing, from which it follows that after finitely many, say s, step...
