On The Hereditary Discrepancy of Homogeneous Arithmetic Progressions
We show that the hereditary discrepancy of homogeneous arithmetic
progressions is lower bounded by . This bound is tight up
to the constant in the exponent. Our lower bound goes via proving an
exponential lower bound on the discrepancy of set systems of subcubes of the
boolean cube .Comment: To appear in the Proceedings of the American Mathematical Societ
Arithmetic properties of Fredholm series for p-adic modular forms
We study the relationship between recent conjectures on slopes of
overconvergent p-adic modular forms "near the boundary" of p-adic weight space.
We also prove in tame level 1 that the coefficients of the Fredholm series of
the U_p operator never vanish modulo p, a phenomenon that fails at higher
level. In higher level, we do check that infinitely many coefficients are
non-zero modulo p using a modular interpretation of the mod p reduction of the
Fredholm series recently discovered by Andreatta, Iovita and Pilloni.Comment: Final version. Numbering in main body different different from

Arithmetic properties of Fredholm series for -adic modular forms
We study the relationship between recent conjectures on slopes of overconvergent -adic modular forms "near the boundary" of -adic weight space. We also prove in tame level 1 that the coeffcients of the Fredholm series of the U operator never vanish modulo , a phenomenon that fails at higher level. In higher level, we do check that infinitely many coefficients are non-zero modulo using a modular interpretation of the mod reduction of the Fredholm series recently discovered by Andreatta, Iovita and Pilloni.Accepted manuscrip
Polignac Numbers, Conjectures of Erd\"os on Gaps between Primes, Arithmetic Progressions in Primes, and the Bounded Gap Conjecture
In the present work we prove a number of surprising results about gaps
between consecutive primes and arithmetic progressions in the sequence of
generalized twin primes which could not have been proven without the recent
fantastic achievement of Yitang Zhang about the existence of bounded gaps
between consecutive primes. Most of these results would have belonged to the
category of science fiction a decade ago. However, the presented results are
far from being immediate consequences of Zhang's famous theorem: they require
various new ideas, other important properties of the applied sieve function and
a closer analysis of the methods of Goldston-Pintz-Yildirim, Green-Tao, and
Zhang, respectively
Shifted distinct-part partition identities in arithmetic progressions
The partition function , which counts the number of partitions of a
positive integer , is widely studied. Here, we study partition functions
that count partitions of into distinct parts satisfying certain
congruence conditions. A shifted partition identity is an identity of the form
for all in some arithmetic progression. Several
identities of this type have been discovered, including two infinite families
found by Alladi. In this paper, we use the theory of modular functions to
determine the necessary and sufficient conditions for such an identity to
exist. In addition, for two specific cases, we extend Alladi's theorem to other
arithmetic progressions
Slopes of modular forms and the ghost conjecture
We formulate a conjecture on slopes of overconvergent p-adic cuspforms of any
p-adic weight in the Gamma_0(N)-regular case. This conjecture unifies a
conjecture of Buzzard on classical slopes and more recent conjectures on slopes
"at the boundary of weight space".Comment: 17 pages. 2 figures. Minor changes from v1. Final version. To appear
