Abstract:

his paper considers the existence of solutions for the following problem:
−u + u + v(x)u = (|u|2 ∗
1
|x|
)u + g(x), x ∈ R3
where v(x) be a continuous function on R3,v(x) < 0, v(x) −→ 0, (as |x| −→ ∞); g(x) ≥
0, g(x) 6≡ 0 and g(x) ∈ H−1(R3). The author proves that there exists a constant C, such
that kg(x)kH−1 ≤ C,then there are at least two solutions for the above problem.

Key words: Multiple solutions, existence, Choquard’s equation
