Donald S. Ornstein mostly deals with Pure mathematics, Ergodic theory, Bernoulli scheme, Bernoulli process and Combinatorics.
His work on Pure mathematics is being expanded to include thematically relevant topics such as Equivalence.
The various areas that Donald S. Ornstein examines in his Ergodic theory study include Discrete mathematics and Invariant measure, Ergodic Ramsey theory, Stationary ergodic process.
Many of his research projects under Discrete mathematics are closely connected to Dynamical systems theory with Dynamical systems theory, tying the diverse disciplines of science together.
He carries out multidisciplinary research, doing studies in Bernoulli process and Stationary process.
The study incorporates disciplines such as Parametrix and Calculus in addition to Combinatorics.
His most cited work include:
- Entropy and isomorphism theorems for actions of amenable groups (531 citations)
- Ergodic theory, randomness, and dynamical systems (390 citations)
- Bernoulli shifts with the same entropy are isomorphic (357 citations)
What are the main themes of his work throughout his whole career to date?
His primary areas of study are Ergodic theory, Discrete mathematics, Pure mathematics, Bernoulli scheme and Mathematical analysis.
The concepts of his Ergodic theory study are interwoven with issues in Stationary ergodic process, Ergodic Ramsey theory and Combinatorics.
His Discrete mathematics study incorporates themes from Transformation, Algebra over a field and Partition.
His Pure mathematics study combines topics from a wide range of disciplines, such as Flow and Aperiodic graph.
Bernoulli scheme and Bernoulli process are commonly linked in his work.
In general Mathematical analysis study, his work on Absolute continuity, Semi-differentiability, Boundary circle and Partial differential equation often relates to the realm of Random walk, thereby connecting several areas of interest.

- Mathematical analysis (16.18%)
- Combinatorics (22.06%)
In recent papers he was focusing on the following fields of study:
His primary scientific interests are in Ergodic theory, Mathematical analysis, Combinatorics, Discrete mathematics and Calculus.
Pure mathematics covers he research in Ergodic theory.
His work in the fields of Differentiable function overlaps with other areas such as Return time.
His work on Absolute continuity, Boundary circle and Partial differential equation as part of general Mathematical analysis study is frequently connected to Double difference, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them.
He interconnects Measure, Stationary process, Algebra over a field and Subsequence in the investigation of issues within Combinatorics.
His Calculus study combines topics in areas such as Point and Isomorphism theorem.
Between 1986 and 2020, his most popular works were:
- Entropy and isomorphism theorems for actions of amenable groups (531 citations)
- How Sampling Reveals a Process (118 citations)
- The differentiability of the conjugation of certain diffeomorphisms of the circle (116 citations)
