diagonal action造句

• But the diagonal action on, i . e . where acts on both and coordinates, may be well-behaved when the action on is not.
• In 2010 he was an invited speaker ( " Application of measure rigidity of diagonal actions " ) at the International Congress of Mathematicians in Hyderabad.
• In an attempt to prove Macdonald's conjecture, introduced the bi-graded module H _ \ mu \, of diagonal harmonics and conjectured that the ( modified ) Macdonald polynomials are the Frobenius image of the character generating function of " H " & mu;, under the diagonal action of the symmetric group.
• The depth of V as an R-module is defined in that paper to be the least positive integer n such that V?" ?" ?" ?" ?" V ( n times V, tensor product of R-modules, diagonal action ) has the same constituent indecomposable modules as V ?" ?" ?" ?" ?" V ( n + 1 times V ) ( not counting multiplicities ).
• Bowditch also gave a topological characterisation of word-hyperbolic groups, thus solving a conjecture proposed by action by homeomorphisms on a perfect metrisable compactum " M " as a " uniform convergence group ", that is such that the diagonal action of " G " on the set of distinct triples from " M " is properly discontinuous and co-compact; moreover, in that case " M " is " G "-equivariantly homeomorphic to the boundary  " " G " of " G ".
