我们定义了一个黑森孤子,即Hessian流形上的黑森流的自相似解。在信息几何中,e-联系是重要的,它与Levi-Civita联系不一致。因此,考虑一个具有平坦联络的Hessian流形与Levi-Civita流形不一致是很有趣的。我们称之为真海森流形。本文证明了任何紧真黑森孤子都是扩张的,任何非平凡紧梯度黑森孤子都是真的。此外,我们证明了Hesse-Einstein流形的对偶空间可以理解为一个黑森孤子。
We define a Hesse soliton, that is, a self-similar solution to the Hesse flow on Hessian manifolds. On information geometry, thee-connection is important, which does not coincide with the Levi–Civita one. Therefore, it is interesting to consider a Hessian manifold with a flat connection which does not coincide with the Levi–Civita one. We call it a proper Hessian manifold. In this paper, we show that any compact proper Hesse soliton is expanding and any non-trivial compact gradient Hesse soliton is proper. Furthermore, we show that the dual space of a Hesse–Einstein manifold can be understood as a Hesse soliton.
