In the space $L_p(\mathbb R^n)$, $1$, we consider a new class of integral operators with kernels homogeneous of degree $-n$, which includes the class of operators with homogeneous $SO(n)$-invariant kernels; we study the Banach algebra generated by such operators with multiplicatively weakly oscillating coefficients. For operators from this algebra, we define a symbol in terms of which we formulate a Fredholm property criterion and derive a formula for calculating the index. An important stage in obtaining these results is the establishment of the relationship between the operators of the class under study and the operators of one-dimensional convolution with weakly oscillating compact coefficients.
Keywords: multidimensional integral operator, operators with multiplicatively weakly oscillating coefficients, homogeneous kernel, convolution operator, the space $L_p(\mathbb R^n)$.
