关于算子─（▽—ia）2＋Ⅴ的性质（Ⅰ）

In this paper,we consider Schrodinger forms (operators) with singular magnetic vectorpotentials ─(▽—ia）²+Ⅴ. We prove that when the negative part V_{_} of electric potentialV satisfies(?) in dependentof V and a=(a₁,a₂,…,a_N)∈L_loc²(R^N)^N, ─(▽—ia）²+Ⅴ has essential self-adjointextension F and it is the only self-adjoint realization of ─(▽—ia）²+Ⅴ. Moreover,We consider the continuity of (a,V) respect to a and V in the sense of strong resolvent.
