Existence of solutions to a self-referred and hereditary system of differential equations

Eduardo Pascali

We establish the existence and uniqueness of a local solution for the system of differential equations
 \frac{\partial }{\partial t}u(x,t)
 = u\Big(v\Big(\int_0^t u(x,s)ds, t\Big), t\Big) \cr
 \frac{\partial }{\partial t}v(x,t)
 = v\Big(u\Big(\int_0^t v(x,s)ds, t\Big), t\Big).
with given initial conditions $u(x,0)=u_0(x)$ and $v(x,0)=v_0(x)$.
