Reconstruction of curves from their theta hyperplanes in genera and
Türkü Özlüm Çelik, David Lehavi
We derive a formula for reconstructing a generic complex canonical curve of genus 6 and 7 in terms of the theta hyperplanes of . Hence, we get a generic inverse to the Torel…
Complete invariants for a comeagre set of compact orientable surfaces in
Yair Hayut, David Lehavi
We introduce invariants for compact -orientable surfaces (with boundary) in up to rigid transformations. Our invariants are certain degree four polynomials in t…
Effective reconstruction of generic genus 5 curves from their theta hyperplanes
David Lehavi
We effectively reconstruct the set of enveloping quadrics of a generic curve C of genus 5 from its theta hyperplanes; for a generic genus 5 curve C this data suffices to effectivel…
Effective reconstruction of generic genus 4 curves from their theta hyperplanes
David Lehavi
Effective reconstruction formulas of a curve from its theta hyperplanes are known classically in genus 2 (where the theta hyperplanes are Weierstrass points), and 3 (where, for a g…
On isogenous principally polarized abelian surfaces
I. Dolgachev, D. Lehavi
We study a relationship between two genus 2 curves whose jacobians are isogenous with kernel equal to a maximal isotropic subspace of p-torsion points with respect to the Weil pair…
