Analytic and coanalytic families of almost disjoint functions
If F N N is an analytic family of pairwise eventually different functions then the following strong maximality condition fails: For any countable H N N, no member of which is cov...

Projective mad families
Using almost disjoint coding we prove the consistency of the existence of a 1 2 definable -mad family of infinite subsets of (resp. functions from to ) together with b = 2 = 2.

Orthogonal quincunx wavelets with fractional orders
We present a new family of 2D orthogonal wavelets which uses quincunx sampling. The orthogonal refinement filters have a simple analytical expression in the Fourier domain as a fu...
