Title: Solvability of some integral equations in Hilbert spaces Author: Onur Alp Ilhan (National Univ. of Uzbekistan, Tashkent, Uzbekistan) Abstract: We consider an integral equation of Fredholm and Volterra type with spectral parameter depending on time. Conditions of solvability are established when the initial value of the parameter coincides with an eigenvalue of Fredholm operator. Submitted August 25, 2004. Published October 5, 2004.
