David kohel thesis

Are covered in david kohel's phd thesis [12] and more recently in [8, 9] 13 complexity model unless otherwise stated all complexity estimations in this paper use elementary bit- wise operations as units we use the standard “big o notation” to describe asymptotic complexities of algorithms recall that for any two functions. Such graphs the definitive work in this area was done by david kohel, whose thesis explicates the structure of isogeny graphs of elliptic curves over finite fields [23] the term “volcano” came later, in work by fouquet and morain [14, 15] that popularized kohel's work and gave one of the first examples of.

Details about computations with supersingular curves see kohel [14] and mestre [23] the paper is organised as methods of kohel's thesis [14] to construct an isogenous elliptic curve e /fp such that end(e ) = z[π] for instance, as david kohel has pointed out, an isogeny is defined as a map of one dimensional group.

In his seminal thesis, kohel describes the structure of the graph of isogenies defined on ellt ( q ) 2 preliminaries kohel's algorithm treats each large prime power pk dividing v by computing the kernel of a david kohel, endomorphism rings of elliptic curves over finite fields, phd thesis of the university of california at. Thanks a lot for the references, they should be very helpful i was also pointed to david kohel's thesis, where (among other results) he provides bounds on the number of elliptic curves isogenous to a given curve c via an isogeny of a given degree he also uses brandt matrices – vesna stojanoska jan 23.

David had implemented code for computing with quaternion algebras, and this was the only implementation of that algorithm in the world my algorithm fundamentally relied on exactly the computations in rational quaternion algebras that david kohel had implemented in magma i had a thesis to finish. The first paper about this topic was my paper constructing isogenies between elliptic curves over finite fields (relying heavily on david kohel's phd thesis) a more useful formulation of the result was given by jao, miller and venkatesan in the paper “do all elliptic curves of the same order have the same.
