Beware of Cat: And Other Encounters of a Letter Carrier

One sunny day on his postal direction, Vincent Wyckoff crosses the trail of an aged gentleman whistling for his misplaced parakeet. The outdated guy is disillusioned, and Wyckoff strikes down the block slowly, taking a look low and high, hoping to identify the little chicken. He reaches the man’s condominium and provides sympathy to his spouse, who smiles unfortunately and says, “We haven’t had that fowl for twenty-five years.

Case (a) above, with A = 0, corresponds to |C| = |D|, and in this case N is a subset of an affine special Lagrangian 3-plane R3 in C3 . If |C| = |D| then N is an embedded submanifold diffeomorphic to R3 , with coordinates (x1 , x2 , t). The two cases C = 0 and D = 0 are constructed by [7, Prop. 3] with n = 2, m = 3 and G = R, as in [7, Ex. 6] and case (c) above, with the symmetry group G of N acting by (x1 , x2 , t) → (x1 , x2 , t + c).

Let us parametrize the circle C+ with a parameter s, so that C+ = x1 (s), x2 (s), x3 (s) : s ∈ R . This gives a parametrization Φ : R2 → Σ+ of Σ+ , by Φ : (s, t) → w1 (t)x1 (s), w2 (t)x2 (s), w3 (t)x3 (s) . 4) We shall calculate the conditions upon xj (s) for Φ to be conformal, and solve them. Since the xj (s) satisfy α1 x12 + α2 x22 + α3 x32 = 1 and x12 − x22 − x32 = 0, differentiating with respect to s gives α1 x1 x˙1 + α2 x2 x˙2 + α3 x3 x˙3 = 0 and x1 x˙1 − x2 x˙2 − x3 x˙3 = 0, where ‘ ˙ ’is dsd .
