Superpolynomially Large Support in Every Irreducible Factor of Lacunary Polynomials

We show that there exist infinitely many polynomials $F\in\mathbb{Q}[x]$ with exactly $m$ nonzero coefficients such that every irreducible factor of $F$ over $\mathbb{Q}$ has $\exp$ $\!\bigl(\Omega(\sqrt{m/\log m})\bigr)$ nonzero coefficients. This places multiplication in a sharply different category from powe...

The Dynamical Mordell--Lang Conjecture for Relatively \'{E}tale Systems over Products of Curves

We establish the dynamical Mordell--Lang conjecture over $\mathbb C$ for endomorphisms that are relatively \'{e}tale over arbitrary endomorphisms of finite products of smooth projective curves. In particular, we establish the conjecture for arbitrary endomorphisms of product of smooth projective curves and relatively...

Dynamical Mordell--Lang Conjecture for Higher-Rank Radially Ramified Skew Products

We establish the dynamical Mordell--Lang conjecture over the complex numbers for a family of radially ramified polynomial skew products in arbitrary base dimension and fiber rank. We assume that one fixed iterate sends the vertical critical locus into the invariant zero section. Our result covers affine-linear bases an...
