👉 Ricciaceous is a term used in mathematics to describe an object or entity that has a curvature similar to that of a Ricci tensor. The Ricci tensor is a quantity that measures the curvature of space, and it can be thought of as a measure of how much space is distorted by a given point. In general relativity, a Ricci scalar is used to quantify the gravitational effects of an object in three spatial dimensions. A Ricci tensor is also used in other areas of mathematics
