Rigidity of amalgamated free products in measure equivalence [PDF]
, 2009 A discrete countable group Γ is said to be ME rigid if any discrete countable group that is ME to Γ is virtually isomorphic to Γ. In this paper, we construct ME rigid groups by amalgamating two groups satisfying rigidity in a sense of measure equivalence.

Atom-Interferometric Test of the Equivalence Principle at the 10^{-12} Level. [PDF]
Physical Review Letters, 2020 We use a dual-species atom interferometer with 2 s of free-fall time to measure the relative acceleration between ^{85}Rb and ^{87}Rb wave packets in the Earth's gravitational field.

Measure equivalence rigidity and bi-exactness of groups [PDF]
, 2009 We get three types of results on measurable group theory; direct product groups of Ozawa's class S groups, wreath product groups and amalgamated free products. We prove measure equivalence factorization results on direct product groups of Ozawa's class S

Dynamic equivalence relation on the fuzzy measure algebras [PDF]
Sahand Communications in Mathematical Analysis, 2017 The main goal of the present paper is to extend classical results from the measure theory and dynamical systems to the fuzzy subset setting. In this paper, the notion of dynamic equivalence relation is introduced and then it is proved that this relation

L2-torsion, the measure-theoretic determinant conjecture, and uniform measure equivalence [PDF]
, 2009 We show an invariance result for the L2-torsion of groups under uniform measure equivalence provided a measure-theoretic version of the determinant conjecture holds.

Limit groups, positive-genus towers and measure-equivalence [PDF]
Ergodic Theory and Dynamical Systems, 2005 By definition, an $\omega$-residually free tower is positive-genus if all surfaces used in its construction are of positive-genus. We prove that every limit group is virtually a subgroup of a positive-genus, $\omega$-residually free tower.

Gromov’s measure equivalence and rigidity of higher rank lattices [PDF]
, 1999 In this paper the notion of Measure Equivalence (ME) of countable groups is studied. ME was introduced by Gromov as a measure-theoretic analog of quasi-isometries.

Journal of Combustion, 2018 The growth of soot volume fraction and aggregate size was studied in burner-stabilized premixed C2H4/air flames with equivalence ratios between 2.0 and 2.35 as function of height above the burner using laser-induced incandescence (LII) to measure soot ...

Measurement Equivalence Testing 2.0
, 2018 Probably the most ignored assumption in the social and behavioral sciences is the assumption that measures are observed without error. Ignoring measurement error when it is present will result in conclusions that are biased to some degree. A second commonly ignored assumption is that survey measures can be used to make valid comparisons between (groups

Measure equivalence rigidity of the mapping class group [PDF]
, 2006 We show that the mapping class group of a compact orientable surface with higher complexity satisfies the following rigidity in the sense of measure equivalence: If the mapping class group is measure equivalent to a discrete group, then they are ...
