Projectively induced Kähler--Einstein surfaces

Andrea Loi, Mirel Caibăr

We classify compact Kähler--Einstein surfaces whose metric is induced by a holomorphic isometric immersion into a finite-dimensional complex projective space. No symmetry assumptio…

Monodromy of Walrasian Equilibrium Prices: A Fixed-Preference Endowment-Redistribution Construction

Andrea Loi, Stefano Matta

Suppose an economy moves continuously along a closed path of fundamentals and returns exactly to its initial state. A regular Walrasian equilibrium price followed continuously alon…

Radial Projectively Induced Canonical Kähler Metrics: Rigidity and Classification

Claudio Arezzo, Andrea Loi, Giovanni Placini +1

We study radial Kähler metrics on domains of , , admitting a Kähler immersion into a finite- or infinite-dimensional complex projective space. We classify th…

Complex Hyperbolic Immersions of Cheng--Yau Metrics on Thullen Domains

Mirel Caibãr, Andrea Loi

For , let \[ M(μ)=\left\{(z,w)\in\mathbb{C}^2 : |z|^2+|w|^{2/μ}<1\right\} \] be the Thullen domain, and let denote its complete Cheng--Yau Kähler--Einstein m…

On Simply Connected Simple Lie Skew Braces with Nilpotent Multiplicative Group

Marco Damele, Andrea Loi

We prove that a simply connected simple Lie skew brace with nilpotent multiplicative Lie group must be one-dimensional and abelian. Equivalently, if is a simply c…

Sorting and Global Uniqueness in Two-Good HARA Economies with Many Patience Types

Andrea Loi, Stefano Matta

We study global uniqueness of competitive equilibrium in two-good pure-exchange economies with heterogeneous impatience types and a common HARA Bernoulli utility. The paper connect…
