Let A be entire. Suppose that there exists an unbounded quasidisk D such that A is sufficiently small in D. We prove that A is sufficiently small in D. We prove that then any nontrivial solution to y″+Ay=0 has at most one zero in D. We show that if A=Q exp P where P and Q are polynomials, one can usually take D to be an angle of opening π/n where n is the degree of P
