👉 In mathematics, a subrigidity is a property of a mathematical object that can be expressed in terms of its geometric properties or topology. A subrigidity is typically defined as a condition that can be visualized using geometric tools such as homology theory, and it can have various implications depending on the specific context. For example, in algebraic geometry, a subrational variety (also known as a subrigid variety) is an algebraic variety where all of its generic points are r
