R. R. Kucharov, Yu. Kh. Eshkabilov National University of Uzbekistan named after M. Ulugbek, Faculty of Mathematics and Mechanics, Tashkent, Uzbekistan
Abstract:
We find the lower boundary for the essential spectrum of a Fredholm type partial integral operator $H$. We also obtain an estimate for the number of eigenvalues below this boundary.
Key words:
essential spectrum, discrete spectrum, the lower boundary of the essential spectrum, Fredholm type partial integral operator.
