摘要
In response to an open problem raised by S. Rabinowitz, we prove that ((x(2) + y(2))(2) + 8y (y(2) - 3x(2)))(2) + 432y (y(2) - 3x(2)) (351 - 10 (x(2) + y(2))) = 567(3) + 28 (x(2) + y(2))(3) + 486 (x(2) + y(2)) (67 (x(2) + y(2)) - 567 x 18) is the equation of a plane convex curve of constant width.
