Abstract
We consider the multidimensional integral operators with bihomogeneous kernels in the L2-space. For such operators, the necessary and sufficient conditions for invertibility is obtained. The main result of the article is the applicability criterion of the projection method to a given class of operators with bihomogeneous kernels.
