| contents | In recent years, the Boussinesq type fractional partial differential equation has attracted much attentions of researchers for its practical importance. In this paper we study a non-local problem for the Boussinesq type equation $D_t^αu(t)+A D_t^αu(t)+ν^2A u(t)=0,\,\, 0< t< T,\,\, 1<α<2,$ where $D_t^α$ is the Caputo fractional derivative and $A$ is abstract operator. In the classical case, i.e. at $α=2$, this problem was studied earlier and an interesting effect was discovered: the well-posedness of the problem significantly depends on the length of the time interval and the parameter $ν$. This note shows that for the case of a fractional equation there is no such effect: the problem is well-posed for any $T$ and $ν$. |
