Integer Points Unusually Close to Elliptic CurvesMarian Vâjâitu and Alexandru ZaharescuInstitute of Mathematics of the Romanian Academy,P.O.

Building, Olden Lane, Princeton, New Jersey 08540 -- USA E-mail: zaharesc@ias.edu Abstract: We consider an elliptic curve $E_{\alpha,\beta}$ given by the equation $Y^2=X^3+\alpha X+\beta$, where $\alpha,\beta$ are real numbers, and look for integer points close to the curve. In case the diophantine type of $\alpha$ is larger than 4 we find infinitely many integer points unusually close to $E_{\alpha,\beta}$ or to the curve $E_{-\alpha,\beta}$. Full text of the article:
