WebThe recession cone (or characteristic cone) of P , denoted by recc ( P), is the set { d ∈ R n: x + λ d ∈ P for all x ∈ P and for all λ ≥ 0 }. Proposition 10.4.

Yet, VRS assumption relaxes the condition of ray unboundedness and is one of the most commonly used assumption in the previous studies and empirical research field. Therefore, our study is also based on VRS. dates through or thru
