Some Structures arising from the Farey Fractal

Shai Haran

This work explores new arithmetic and combinatorial structures arising from the interplay between Farey-type graphs, Fibonacci expansions, and operadic constructions. We introduce…

Non Additive Geometry

Shai Haran

The usual dictionary between geometry and commutative algebra is not appropriate for Arithmetic geometry because addition is a singular operation at the "Real prime". We replace Ri…

Non-Additive Geometry and Frobenius Correspondences

Shai Haran

The usual language of algebraic geometry is not appropriate for Arithmetical geometry: addition is singular at the real prime. We developed two languages that overcome this problem…

Homotopy and Arithmetic

Shai Haran

We define the concept of a bi-operad. We develop the homotopy theory of "Bital-Sets" and of infinite-bi-operads. We develop a geometry of generalized schemes based on the spectra o…

Meditations on the Farey Fractal

Shai Haran

We study the paths in the Farey graph going from (1,0) to (0,1) , or the finite subtrees of the Stern-Brocot tree . We show they form an operad and isolate the "coronas", which are…

Algebra over generalized rings

Shai Haran

For a commutative ring , we have the category of (bounded-below) chain complexes of -modules $Ch_{+}(A\mymod)$, a closed symmetric monoidal category with a compatible stable…

Geometry over F1

Shai Haran

We give (two) non additive languages for geometry via simple generalisations of commutative rings.

New foundations for geometry

Shai Haran

We shall describe a simple generalization of commutative rings. The category GR of such "rings", contains the ordinary commutative rings (fully faithfully), but also the "integers"…

Non-Additive Prolegomena (to any future Arithmetic that will be able to present itself as a Geometry)

Shai M. J. Haran

We give a language for geometry which makes curves and number fields look alike.
