# homologically trivialの例文

- where Z ^ k ( X ) denotes the group of algebraic cycles of some fixed codimension " k " and the subscripts indicate the groups that are
*homologically trivial*, respectively algebraically equivalent to zero. - It follows that a compact K鋒ler Einstein manifold " X " must have canonical bundle " K " " X " either anti-ample,
*homologically trivial*, or Calabi Yau, or with ample canonical bundle ( which implies general type ), respectively. - In mathematics, especially in the area of algebraic topology known as stable homotopy theory, the "'Adams filtration "'and the "'Adams-Novikov filtration "'allow a stable homotopy group to be understood as built from layers, the " n " th layer containing just those maps which require at most " n " auxiliary spaces in order to be a composition of
*homologically trivial* maps.
