Singularity formations for a surface wave model
(IOP Publishing, 2010-11)In this paper we study the Burgers equation with a nonlocal term of the form Hu where H is the Hilbert transform. This ...

Some bounds and limits in the theory of Riemann's zeta function
(Elsevier, 2012-12-01)For any real a > 0 we determine the supremum of the real σ such that ζ(σ+it) = a for some real t. For 0 < a < 1, a = 1, ...
