Extendable codimension two subvarieties in a general hypersurface
G. V. Ravindra, Debaditya Raychaudhury
We exhibit a class of extendable codimension subvarieties in a general hypersurface of dimension at least in projective space. As a consequence, we prove that a general hyp…

Calibrated submanifolds with flat normal bundles
W. Jacob Ogden
We show that submanifolds of Euclidean space which are calibrated by a constant-coefficient differential form and have flat normal bundles are planes. In fact, in a Riemannian mani…

Zero-free regions near a line
Kelly Bickel, J. E. Pascoe, Meredith Sargent
We analyze metrics for how close an entire function of genus one is to being real rooted. These metrics arise from truncated Hankel matrix positivity-type conditions built from pow…
