Usage notes [ edit ] In some contexts, (e.g., universal algebra ), an epimorphism may be defined as a surjective homomorphism , and the definition of isogeny may change accordingly. Isogeny formulas for Jacobi intersection and twisted hessian curves. Advances in Mathematics of Communications , 2020, 14 (3) : 507-523. doi: 10.3934/amc.2020048 the image of a rational isogeny, is shown to possess a uniformly bounded number of prime terms. This result applies over the rational numbers, assuming Lang’s conjecture, and over the rational function ﬁeld, uncon-ditionally. In the latter case, a uniform bound is obtained on the index of a prime term.

An isogeny overF q as˚: E!E0asanon-constantrationalmapfrom E(F q) to Lange, Martindale, Panny, and Renes [7] in 2018. CSIDH restricts the isogeny isogeny-based cryptography, namely how to hash into a supersingular isogeny graph without revealing a path to a known base curve. This problem remains open both in the SIDH (full isogeny graph) Choosing safe post-quantum parametersfor the new CSIDH isogeny-based key-exchange systemrequires concrete analysis of the cost of quantum attacks. The two main contributions to attack cost arethe number of queries in hidden-shift algorithmsand the cost of each query.

This is an isogeny, because the multiplication map can be expressed with rational functions on the coordinates of the point. See for example Chapter 3, Section 4, of The Arithmetic of Elliptic Curves by Silverman (titled "Isogenies"). Isogeny comes from iso and genus, "equal origin." Added.
