Riemannian Metric Affinor Structure Almost Conformal Transformation
University Press "Paisii Hilendarski", Plovdiv
We consider a 3-dimensional Riemannian manifold V with a
metric g and an a±nor structure q. The local coordinates of these tensors are
circulant matrices. In V we define an almost conformal transformation. Using
that definition we construct an infinite series of circulant metrics which are
successively almost conformaly related. In this case we get some properties.
