Extending linear and quadratic functions from high rank varieties

David Kazhdan, Tamar Ziegler

Let $k$ be a field, $V$ be a $k$ -vector space and $X \subset V$ an algebraic irreducible subvariety. We say that a function $f : X (k) \to k$ is weakly linear if its restriction to any…

Polynomial functions as splines

David Kazhdan, Tamar Ziegler

Let $V$ be a vector space over a finite field $k$ . We give a condition on a subset $A \subset V$ that allows for a local criterion for checking when a function $f : A \to k$ is a res…

Appoximate Cohomology

David Kazhdan, Tamar Ziegler

Let $k$ be a field, $G$ be an abelian group and $r \in N$ . Let $L$ be an infinite dimensional $k$ -vector space. For any $m \in E n d_{k} (L)$ we denote by $r (m) \in [0, \infty]$ th…

On the bias of cubic polynomials

David Kazhdan, Tamar Ziegler

Let $V$ be a vector space over a finite field $k = F_{q}$ of dimension $n$ . For a polynomial $P : V \to k$ we define the bias of $P$ to be $$b_1(P)=\frac {|\sum _{v\in V}ψ(P(V))…
