C-ALGEBRA GENERATED BY INTEGRAL OPERATORS WITH HOMOGENEOUS KERNELS AND OSCILLATING COEFFICIENTS OF VARIOUS TYPES

We consider the C*-algebra, generated by multidimensional integral operators with homogeneous degree ( - n ) kernels and by the operators of multiplication by radial weak oscillating functions and by oscillating functions of the form | x | i α . For this algebra, an operator symbolic calculus is con...

description We consider the C*-algebra, generated by multidimensional integral operators with homogeneous degree ( - n ) kernels and by the operators of multiplication by radial weak oscillating functions and by oscillating functions of the form | x | i α . For this algebra, an operator symbolic calculus is constructed. In terms of this calculus, necessary and sufficient conditions for the Fredholm property of an operator are obtained.
