A mapping ϕ of a groupG to a groupF is said to be polynomial if it trivializes after several consecutive applications of operatorsDh,h ∈G, defined byDhϕ(g)=ϕ(g)−1ϕ(gh). We study polynomial mappings of groups, mainly to nilpotent groups. In particular, we prove that polynomial mappings to a nilpotent group form a group with respect to the elementwise multiplication, and that any polynomial mappingG→F to a nilpotent groupF splits into a homomorphismG→G’ to a nilpotent groupG’ and a polynomial… Expand
Polynomials and harmonic functions on discrete groups
Alexopoulos proved that on a finitely generated virtually nilpotent group, the restriction of a harmonic function of polynomial growth to a torsion-free nilpotent subgroup of finite index is always aExpand
Higher order Fourier analysis as an algebraic theory III
For every natural number k we introduce the notion of k-th order convolution of functions on abelian groups. We study the group of convolution preserving automorphisms of function algebras in theExpand
Abstract We introduce a refined version of group cohomology and relate it to the space of polynomials on the group in question. We show that the polynomial cohomology with trivial coefficients admitsExpand
Classification of Polynomial Mappings Between Commutative Groups
Some polynomials $P$ with rational coefficients give rise to well defined maps between cyclic groups, $\Z_q\longrightarrow\Z_r$, $x+q\Z\longmapsto P(x)+r\Z$. More generally, there are polynomials inExpand
Regularity and inverse theorems for uniformity norms on compact abelian groups and nilmanifolds
We prove a general form of the regularity theorem for uniformity norms, and deduce a generalization of the Green-Tao-Ziegler inverse theorem, extending it to a class of compact nilspaces includingExpand
Gowers norms, regularization and limits of functions on abelian groups
For every natural number k we prove a decomposition theorem for bounded measurable functions on compact abelian groups into a structured part, a quasi random part and a small error term. In thisExpand
Distribution of values of bounded generalized polynomials
A generalized polynomial is a real-valued function which is obtained from conventional polynomials by the use of the operations of addition, multiplication, and taking the integer part; a generalizedExpand
Polynomial maps and polynomial sequences in groups
This paper develops a theory of polynomial maps from commutative semigroups to arbitrary groups and proves that it has desirable formal properties when the target group is locally nilpotent. We willExpand
Higher order mixing and rigidity of algebraic actions on compact Abelian groups
Let Γ be a discrete group and fori=1,2; letαi be an action of Γ on a compact abelian groupXi by continuous automorphisms ofXi. We study measurable equivariant mapsf: (X1,α1)→(X2,α2), and prove aExpand
Waring's Problem For Locally Nilpotent Groups: The Case of Discrete Heisenberg Groups
Kamke \cite{Kamke1921} solved an analog of Waring's problem with $n$th powers replaced by integer-valued polynomials. Larsen and Nguyen \cite{LN2019} explored the view of algebraic groups as aExpand


Polynomial Sequences in Groups

Let $G$ be a finitely generated nilpotent group of unitary operators on a Hilbert space ${\cal H}$. We prove that ${\cal H}$ is decomposable into a direct sum ${\cal H}=\bigoplus_{\alpha\in A}{\calExpand
A nilpotent Roth theorem
Abstract.Let T and S be invertible measure preserving transformations of a probability measure space (X, ℬ, μ). We prove that if the group generated by T and S is nilpotent, then Expand
On sets of integers containing k elements in arithmetic progression
In 1926 van der Waerden [13] proved the following startling theorem : If the set of integers is arbitrarily partitioned into two classes then at least one class contains arbitrarily long arithmeticExpand
