Abstract
This note studies the Schrodinger-Choquard equation with an inhomogeneous combined source term and a fractional Laplacian operator
iu - (-Delta)(s)u = +/-vertical bar x vertical bar(b)vertical bar u vertical bar(2(p-1))u +/- (I-alpha (*) vertical bar u vertical bar(q))vertical bar u vertical bar(q-2)u
Indeed, for b not equal 0 and 0 < s < 1, one obtains a sharp threshold of global existence versus finite time blow-up dichotomy for mass-super-critical and energy sub-critical radial solutions.
