Let ϕ: X → X be a morphism of a variety over a number field K. We consider local conditions and a “Brauer-Manin” condition, defined by Hsia and Silverman, for the orbit of...
Tropical geometry is sensitive to embeddings of algebraic varieties inside toric varieties. The purpose of this paper is to advertise tropical modifications as a tool to locally r...
Let L(t) represent the equation x1 + x2 + · · · + xt−1 = xt. For k 1, 0 i k − 1, and ti 3, the generalized Schur number S(k; t0, t1, . . . , tk−1) is the least positive i...
