The center of an ellipse is the midpoint of both the major and minor axes. The axes are perpendicular at the center. The foci always lie on the major axis, and the sum of the distances from the foci to any point on the ellipse (the constant sum) is greater than the distance between...

Ellipse, a closed curve, the intersection of a right circular cone (see cone) and a plane that is not parallel to the base, the axis, or an element of the cone. It may be defined as the path of a point moving in a plane so that the ratio of its distances
The set of all points in a plane, the sum of whose distances from two fixed points in the plane is constant is an ellipse. These two fixed points are the foci of the ellipse (Fig. 1). When a line segment is drawn joining the two focus points, then the mid-point of this line is...
elliptic equationsThe present paper considers the Dirichlet problem for properly elliptic equations of fourth order in the exterior of an ellipse. No restrictions on the multiplicities of the roots of the characteristic polynomial are assumed.doi:10.3103/S1068362308020040A. Sahakyan...
