    • Best coapproximation in L∞(µ, X) 

      Jawdat, Jamila (Işık University Press, 2018)
      Let X be a real Banach space and let G be a closed subset of X. The set G is called coproximinal in X if for each x ∈ X, there exists y₀ ∈ G such that ||y − y₀|| ≤ ||x – y|| , for all y ∈ G. In this paper, we study ...
