In this talk we are concerned with a three-body system with point interaction, which is called the Ter-Martirosian--Skornyakov extension. We locate the bottom of the essential spectrum of that system and establish the finiteness of the discrete spectrum below the bottom. Our work here refines the result of R. A. Minlos (Mosc. Math. J. 11 (2011), 113--127), where the semi-boundedness of the operator is obtained.

Different day of the week.
