Gröbner bases beat the classical modular-polynomial setup here, for 2^k and 3^k supersingular isogenies.

Can Richelot (2,2) isogenies be done without derivatives? This paper says yes, via subresultants and algebraic checks.

Models supersingular isogenies of 2^k and 3^k degree as zero-dimensional polynomial systems, then pokes Gröbner bases at them.

Paper on EUF-CMA proofs for higher-dimensional SQIsign with pushable hints, because signature security apparently needed more hints.

Computational PPAV framework, with theta-model algorithms for automorphism groups and higher-dimensional isogeny interpolation.

Preprint on an adaptive attack on FESTA variants with masked-degree isogenies, plus the usual exception list.

Can WayFinder generalize Delfs-Galbraith/SuperSolver to oriented curves and shave isogeny attack costs?

Reduces supersingular endomorphisms to splitting abelian surfaces, then heuristically equates the dim-2 degree-bounded versions.

A post-quantum commitment scheme from punctured Richelot isogeny walks on genus-2 Jacobians, with a SageMath prototype.

Paper on randomizable isogeny signatures, extending SQIsign/PRISM/DeuringVUF with unlinkability proofs; more algebra, less drama.

A categorical wrapper around Deuring/SQIsign that spits out ID, signatures, and chameleon hashes, plus two isogeny instantiations.
