Jun Bo Lau, Travis Morrison, Eli Orvis +2
We introduce a ``non-orientable'' variation of Serre's definition of a graph, which we call an abstract isogeny graph. These objects capture the combinatorics of the graphs $G(p,\e…

The SEA algorithm for endomorphisms of supersingular elliptic curves
Travis Morrison, Lorenz Panny, Jana Sotáková +1
For a prime and a supersingular elliptic curve defined over with , consider an endomorphism of represented as a c…
