  6. Finsler's lemma - Wikipedia

    en.wikipedia.org/wiki/Finsler's_lemma

    Finsler's lemma can be used to give novel linear matrix inequality (LMI) characterizations to stability and control problems. [4] The set of LMIs stemmed from this procedure yields less conservative results when applied to control problems where the system matrices has dependence on a parameter, such as robust control problems and control of ...

    In mathematics, there are many kinds of inequalities involving matrices and linear operators on Hilbert spaces. This article covers some important operator inequalities connected with traces of matrices. [1] [2] [3] [4]

  8. Loewner order - Wikipedia

    en.wikipedia.org/wiki/Loewner_order

    If A or B is a multiple of the identity matrix, then this criterion is also necessary. The Loewner order does not have the least-upper-bound property, and therefore does not form a lattice. It is bounded: for any finite set of matrices, one can find an "upper-bound" matrix A that is greater than all of S. However, there will be multiple upper ...

  9. Korn's inequality - Wikipedia

    en.wikipedia.org/wiki/Korn's_inequality

    Korn's theorem is a quantitative version of this statement, which intuitively says that if the gradient of a vector field is on average not far from the space of skew-symmetric matrices, then the gradient must not be far from a particular skew-symmetric matrix. The statement that Korn's inequality generalizes thus arises as a special case of ...
