👉 Submanic is a concept in mathematics, particularly in topology and algebraic geometry. It refers to an object that behaves like a submanifold but lacks all geometric properties of a manifold. In topology, a submanifold is an embedded submanifold (i.e., the boundary of a manifold) that is homeomorphic to a subset of Euclidean space. A submanifold in this context can be thought of as an abstract mathematical object that is locally similar to but not identical to a
