In the present paper, we introduce the notion of a singular integral with the Cauchy kernel for distributions and consider a singular integral equation with the Cauchy kernel on a closed interval for the case in which the right-hand side is a distribution that admits a representation in the form of the sum of a distribution vanishing in neighborhoods of the endpoints and an ordinary function satisfying the Hölder condition. The solution is also sought in the form of a distribution. Distributions are treated as linear functionals on some test functions. We analyze the solvability of the equation in the class of distributions and obtain explicit formulas for the inversion of this equation, similar to formulas for ordinary solutions. To analyze the solvability of the singular integral equation, we use an approach based on the consideration of the Riemann boundary value problem for analytic functions with a generalized boundary condition. When stating and studying this problem, we use the results in [1,2].
