how to solve this set of integro-differential equations analytically?












1












$begingroup$


I'm stuck with the following system of integro-differential equations and I need to know if it can be analytically solved or not.
$$dot{f}(x)+ a_1 f(x) + a_2int_{x_0}^x k(x,y) f(y) dy+a_3= b_1 g(x)+b_2 int_{x_0}^x k(x,y) g(y) dy $$
$$dot{g}(x)+ c_1 g(x) +c_2 int_{x_0}^x k(x,y) g(y) dy+c_3= d_1 f(x)+ d_2int_{x_0}^x k(x,y) f(y) dy$$
Excluding $f$ and $g$, all function and coefficients are known.



Please let me know if you have any idea for solving this or any clue to better search for the answer.
