“…Due to the presence of non-integrable singularities in the integral kernels ) , , ( 33 k F ω y x , Eq. (11), whose rank exceeds the dimension of the integration region, the appropriate integrals in the system (12) are hypersingular and should be treated in the sense of the Hadamard finite part, see, for instance, Martin et al (1989), Kilic and Madenci (2007), Men'shikov et al (2007), . The structure of integrals depends on the types of the weight and trial functions.…”
