- Hastings, S. P., and Troy, W. C. "A Shooting Approach to the Lorenz Equations"
-
- Abstract. We announce the outline of a proof of the existence of a
- homoclinic orbit of the Lorenz equations. In addition, we develop a
- shooting technique and two key conditions, which lead to the existence
- of a one-to-one correspondence between a set of solutions and the set
- of all infinite sequences of 1's and 3's.
