Abstract :
In this paper, we study the solvability of two operator equations 𝐴 𝑋 𝐵 + 𝑋^∗ = 𝐶 (1) and 𝐴 𝑋 𝐵 + 𝐵^∗𝑋^∗𝐶 = 𝐷 (2) Where A, B, C and D are bounded linear operators. We give the necessary and sufficient conditions for the existence of a solution of equation (1), and describe the general form of the solution in the solvable case for both equations by using g-inverse of the operator B.
