Pointwise Convergence of Sequences of Singular Measures

Andrew Parrish, Joseph Rosenblatt

We investigate the almost everywhere convergence of sequences of convolution operators given by probability measures on . If this sequence of operators constitutes…

Ergodic Theory and Diophantine approximation for translation surfaces and linear forms

Jayadev Athreya, Andrew Parrish, Jimmy Tseng

We derive results on the distribution of directions of saddle connections on translation surfaces using only the Birkhoff ergodic theorem applied to the geodesic flow on the moduli…

Perturbation of Sparse Ergodic Averages

Andrew Parrish

We provide examples of a nested sequences of sets {S_n}, suitably sparse, residing in a group G, for which multidimensional averages fail converge pointwise for f in certain L^p sp…

Multivariable averaging on sparse sets

Patrick LaVictoire, Andrew Parrish, Joseph Rosenblatt

Nonstandard ergodic averages can be defined for a measure-preserving action of a group on a probability space, as a natural extension of classical (nonstandard) ergodic averages. W…

Three Proofs of the Hypergraph Ramsey Theorem (An exposition)

William Gasarch, Andy Parrish, Sandow Sinai

Ramsey, Erdos-Rado, and Conlon-Fox-Sudakov have given proofs of the 3-hypergraph Ramsey Theorem with better and better upper bounds on the 3-hypergraph Ramsey Number. Ramsey and Er…

An additive version of Ramsey's theorem

Andy Parrish

We show that, for every , there is an so that any -coloring of the edges of the complete graph on will yield a monochromatic complete subgraph on vertic…

Toward a graph version of Rado's theorem

Andy Parrish

An equation is called graph-regular if it always has monochromatic solutions under edge-colorings of the complete graph on the naturals. We present two Rado-like conditions which a…

Pointwise Convergence of Ergodic Averages in Orlicz Spaces

Andrew Parrish

We show that for each Orlicz space properly contained in L^1 there is a sequence along which the ergodic averages converge for functions in the Orlicz space, but diverge for all f…
