Necessary and sufficient conditions on the weight functions
$u(.)$ and $v(.)$ are derived in order that the
fractional maximal operator $M_\alpha$,
$0\le\alpha<1$, is bounded from the weighted amalgam space
$\ell^s(L^p(\Bbb R,v(x)dx))$ into $\ell^r(L^q(\Bbb R,u(x)dx))$ whenever
$1
fractional integral operator $I_\alpha$, $0<\alpha<1$, is also studied.
Keywords: weighted inequalities, fractional maximal operators, fractional integral operators, amalgam spaces
