We prove that the moduli space of rational curves with cyclic action, constructed in our previous work, is realizable as a wonderful compactification of the complement of a hyperplane arrangement in a product of projective spaces. By proving a genera

Let f : P n → P n f:{\mathbb P}^n\to {\mathbb P}^n be a morphism of degree d ≥ 2 d\ge 2 . The map f f is said to be post-critically finite (PCF) if there exist integers k ≥ 1 k\ge 1 and ℓ ≥ 0 \ell \ge 0 such that the critical locus Crit f \

The moduli space M ¯ 0 , n \overline {\mathcal {M}}_{0,n} carries a codimension- d d Chow class κ d \kappa _{d} . We consider the subspace K n d \mathcal {K}^{d}_{n} of A d ( M ¯ 0 , n , Q ) A^d(\overline {\mathcal {M}}_{0,n},\mathbb {Q}) spanned

Let ϕ : S 2 → S 2 \phi :S^2 \to S^2 be an orientation-preserving branched covering whose post-critical set has finite cardinality n n . If ϕ \phi has a fully ramified periodic point p ∞ p_{\infty } and satisfies certain additional conditions, t

We define a moduli space of rational curves with finite-order automorphism and weighted orbits, and we prove that the combinatorics of its boundary strata are encoded by a particular polytopal complex that also captures the algebraic structure of a c

Hurwitz correspondences are certain multi-valued self-maps of the moduli space M 0 , N . They arise in the study of Thurston's topological characterization of rational functions. We compare the dynamics of Hurwitz correspondence H on two different co

We focus on various dynamical invariants associated to toric correspondences, using algebraic geometry or arithmetic. We find a formula for the dynamical degrees, relate the exponential growth of the degree sequences with a strict log-concavity condi

Extant eukaryotic cells have a dynamic traffic network that consists of diverse membrane-bound organelles exchanging matter via vesicles. This endomembrane system arose and diversified during a period characterized by massive expansions of gene famil

Communities of interdependent microbes, found in diverse natural contexts, have recently attracted the attention of bioengineers. Such consortia have potential applications in biosynthesis, with metabolic tasks distributed over several phenotypes, an
