a family of 3-dimensional steady gradient ricci solitons that are flying wings
abstract:
we find a family of 3d steady gradient ricci solitons that are flying wings. this verifies a conjecture by hamilton. for a 3d flying wing, we show that the scalar curvature does not vanish at infinity. the 3d flying wings are collapsed. for dimension $n \geq 4$, we find a family of $\mathbb{z}_2 \times o(n − 1)$-symmetric but non-rotationally symmetric n-dimensional steady gradient solitons with positive curvature operator. we show that these solitons are non-collapsed.
