The bounded and S-concordant solutions of the quasilinear total differential equations with a real parameter by the nonlinearity and with a regular homogeneous part are investigated.
In this study there are established relations between the solutions of singular integral equations and equations which are obtained as a result of their regularization and conditions that ensure equivalence of these ...
In the work it is shown a method to regularize singular integral equations which contain operator of complex conjugation or translation operator of Carleman type.
