In this note the point-like interaction of n fermions with a particle of a different nature is considered in a framework of the theory of self-adjoint extensions of symmetric operators. It introduces the family of extensions of the original symmetric operator, most natural from the physical point of view (the so-called Ter-Martirosian–Skornyakov’ extensions). Here we prove that for n 6 4 and large enough values of the mass of the separate particle these extensions are self-adjoint and bounded from below. 2000 Math. Subj. Class. 81Q10, 47S30.
