  "Description": "An R implementation of Matthew Thomas's 'Python' library\n'inteq'. First, this solves Fredholm integral equations of the\nfirst kind ($f(s) = \\int_a^b K(s, y) g(y) dy$) using methods\ndescribed by Twomey (1963) <doi:10.1145/321150.321157>. Second,\nthis solves Volterra integral equations of the first kind\n($f(s) = \\int_0^s K(s,y) g(t) dt$) using methods from Betto and\nThomas (2021) <doi:10.48550/arXiv.2106.08496>. Third, this\nsolves Voltera integral equations of the second kind ($g(s) =\nf(s) + \\int_a^s K(s,y) g(y) dy$) using methods from Linz (1969)\n<doi:10.1137/0706034>.",
