The evolution of the entropy uncertainty (the blue solid line), its lower bound (the red solid line), and the negativity (the cyan dotted line) in no SGI ( θ=0 ) and considering the initial state in maximum entanglement for different non-Markov strengths: (a) λ=γ ; (b) λ=0.1γ ; (c) λ=0.01γ ; (d) λ=0.001γ .
