An special example of an integral equation

104 Views Asked by At

How can solve the following special integral equation:

$$\int_0^x \frac{x^2 t^3 + t^4 +1}{(x-t)^{\frac{1}{4}}}u(t)\; dt=\frac{128}{231}x^{\frac{11}{4}}+\frac{32768}{100947}x^{\frac{31}{4}}+\frac{262144}{908523}x^{\frac{27}{4}}$$ with $0\leq x\leq 1$?

Which method is suitable for solving it?

I suppose you don't want one to 'show' the solution $u$, but if you would like to know what bibliography has to offer, consider this article on AMS. It mentions that Volterra considers

$$\phi(x) - \phi(a) = \int_a^x\,\frac{G(x,t)}{{(x-t)}^\lambda}\,u(t)\,dt,$$

where $\lambda<1$, $G(x,t)$ and $\partial G/\partial x$ are continuous in the triangular region $a \leq t \leq x \leq b$ and $G(x,x)\neq 0$. It says

"this generalization Volterra carries out in the second of his papers appearing in the Atti di Torino, and shows that there is one and only one continuous solution."

Hence, with $a=0$, $b=1$, $\lambda = 1/4$, $G(x,t) = x^2t^3+t^4+1$ and

$$\phi(x) = \frac{128}{231}x^{\frac{11}{4}}+\frac{32768}{100947}x^{\frac{31}{4}}+\frac{262144}{908523}x^{\frac{27}{4}},$$

your equation has a unique continuous solution $u$.
