Entire functions sharing one value with linear differential polynomials

A Non-zero Value Shared by an Entire Function and its Linear Differential Polynomials

“…Since by the hypothesis E 1) (a; L (1) ) ⊂ E(a; f ), we get E(a; L (1) ) = E(a; f ). Since E(a; L (1) ) = E(a; f ) = E 1) (a; f ) ⊂ E(a; f (1) ) and from (3.3) we get L (3) = φ f (1) , each a-point of L (1) is a double a-point. Therefore, (3.12)…”
