  2. Gromov's theorem on groups of polynomial growth - Wikipedia

    en.wikipedia.org/wiki/Gromov's_theorem_on_groups...

    rank denotes the rank of an abelian group, i.e. the largest number of independent and torsion-free elements of the abelian group. In particular, Gromov's theorem and the Bass–Guivarc'h formula imply that the order of polynomial growth of a finitely generated group is always either an integer or infinity (excluding for example, fractional powers).

  3. Non-squeezing theorem - Wikipedia

    en.wikipedia.org/wiki/Non-squeezing_theorem

    The non-squeezing theorem, also called Gromov's non-squeezing theorem, is one of the most important theorems in symplectic geometry. [1] It was first proven in 1985 by Mikhail Gromov. [2] The theorem states that one cannot embed a ball into a cylinder via a symplectic map unless the radius of the ball is less than or equal to the radius of the ...

    One of Gromov's compactness theorems: Gromov's compactness theorem (geometry) in Riemannian geometry; Gromov's compactness theorem (topology) in symplectic topology; Gromov's Betti number theorem Gromov–Ruh theorem on almost flat manifolds; Gromov's non-squeezing theorem in symplectic geometry; Gromov's theorem on groups of polynomial growth

  5. Gromov's compactness theorem (geometry) - Wikipedia

    en.wikipedia.org/wiki/Gromov's_compactness...

    The role of this theorem in the theory of Gromov–Hausdorff convergence may be considered as analogous to the role of the Arzelà–Ascoli theorem in the theory of uniform convergence. [2] Gromov first formally introduced it in his 1981 resolution of the Milnor–Wolf conjecture in the field of geometric group theory , where he applied it to ...

  7. Growth rate (group theory) - Wikipedia

    en.wikipedia.org/wiki/Growth_rate_(group_theory)

    The free abelian group has a polynomial growth rate of order d. The discrete Heisenberg group H 3 {\displaystyle H_{3}} has a polynomial growth rate of order 4. This fact is a special case of the general theorem of Hyman Bass and Yves Guivarch that is discussed in the article on Gromov's theorem .

  9. Bishop–Gromov inequality - Wikipedia

    en.wikipedia.org/wiki/Bishop–Gromov_inequality

    In mathematics, the Bishop–Gromov inequality is a comparison theorem in Riemannian geometry, named after Richard L. Bishop and Mikhail Gromov. It is closely related to Myers' theorem , and is the key point in the proof of Gromov's compactness theorem .
