from Wikipedia, the free encyclopedia

The word unimodularity describes various properties in mathematics :

  • A unimodular affinity has determinants .
  • A unimodular form is a bilinear form whose associated matrix is ​​unimodular.
  • A unimodular grid is a grid with discriminants .
  • A unimodular group is a locally compact topological group whose left and right hair measurements coincide.
  • A unimodular complex number has magnitude , a unimodular function has complex values ​​of magnitude .
  • Depending on the definition, a matrix is ​​called unimodular if:
  • A unimodular transformation is a linear transformation with whole rational coefficients and determinants .
  • A (finite-dimensional) Hopf algebra is unimodular if and only if every left integral is also a right one.
