چکیده
Abstract We prove two theorems concerning isogenies of elliptic curves over function fields. The first one describes the variation height $j$-invariant in an isogeny class. second is “isogeny estimate,” providing explicit bound on degree a minimal between isogenous curves. also give several corollaries these results.

Constructing Isogenies between Elliptic Curves over Finite Fields
Let E1 and E2 be ordinary elliptic curves over a finite field Fp such that #E1(Fp) = #E2(Fp). Tate’s isogeny theorem states that there is an isogeny from E1 to E2 which is defined over Fp. The goal of this paper is to describe a probabilistic algorithm for constructing such an isogeny. The algorithm proposed in this paper has exponential complexity in the worst case. Nevertheless, it is efficie...
متن کاملRanks of elliptic curves over function fields
We present experimental evidence to support the widely held belief that one half of all elliptic curves have infinitely many rational points. The method used to gather this evidence is a refinement of an algorithm due to the author which is based upon rigid and crystalline cohomology.
متن کاملIsogenies of Supersingular Elliptic Curves over Finite Fields and Operations in Elliptic Cohomology
In this paper we investigate stable operations in supersingular elliptic cohomology using isogenies of supersingular elliptic curves over nite elds. Our main results provide a framework in which we give a conceptually simple new proof of an elliptic cohomology version of the Morava change of rings theorem and also gives models for explicit stable operations in terms of isogenies and morphisms i...
متن کاملHYPERELLIPTIC MODULAR CURVES X0(n) AND ISOGENIES OF ELLIPTIC CURVES OVER QUADRATIC FIELDS
Let n be an integer such that the modular curve X0(n) is hyperelliptic of genus ≥ 2 and such that the Jacobian of X0(n) has rank 0 over Q. We determine all points of X0(n) defined over quadratic fields, and we give a moduli interpretation of these points. As a consequence, we show that up to Q-isomorphism, all but finitely many elliptic curves with n-isogenies over quadratic fields are in fact ...
متن کاملON THE NUMBER OF n-ISOGENIES OF ELLIPTIC CURVES OVER NUMBER FIELDS
We find the number of elliptic curves with a cyclic isogeny of degree n over various number fields by studying the modular curves X0(n). We show that for n = 14, 15, 20, 21, 49 there exist infinitely many quartic fields K such that #Y0(n)(Q) 6= #Y0(n)(K) < ∞. In the case n = 27 we prove that there are infinitely many sextic fields such that #Y0(n)(Q) 6= #Y0(n)(K) < ∞.
