Let X be a non-singular irreducible complex projective curve of genus g ≥ 2. The concept of stability of coherent systems over X depends on a positive real parameter α, given then a (finite) family of moduli spaces of coherent systems. We use (t, l)-stability to prove the existence of coherent systems over X that are α-stable for all allowed α > 0.
