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…

Towards the inductive McKay--Navarro Condition for groups of Lie type
Lucas Ruhstorfer, A. A. Schaeffer Fry, Britta Späth +1
We gather tools for proving the inductive McKay--Navarro (or Galois--McKay) condition for groups of Lie type and odd primes. We use this to establish a bijection in the case of qua…
