👉 In mathematics, a seminvariantive is a type of matrix or linear operator that satisfies certain properties. These properties include being positive definite (positive semi-definite), having an inverse that is also positive definite, and not being diagonally dominant. A positive semi-definite matrix is one whose eigenvalues are all positive. A symmetric matrix is positive semidefinite if its transpose is also positive semidefinite. An invertible matrix has a unique inverse, which means it is non-zero for every

What is the definition of Seminvariant? 🙋
👉 In mathematics, a seminvariant is a concept used in the field of dynamical systems. It refers to a property that does not depend on initial conditions or parameters but remains constant under small perturbations. A seminvariant can be defined as an invariant which also has some sort of "seminormality" - it is invariant under all transformations (by itself) and is not affected by the presence of any other transformations. In other words, if a dynamical system is described by
