Improved Torsion-Point Attacks on SIDH Variants
Annual International Cryptology Conference, 2020SIDH is a post-quantum key exchange algorithm based on the presumed difficulty of finding isogenies between supersingular elliptic curves. However, SIDH and related cryptosystems also reveal additional information: the restriction of a secret isogeny to ...

Cuspidal q-Rational Torsion Subgroup of J(G) of Level P
, 2011For $p\!>\!3$ an odd prime, let $\Gamma$ be a congruence subgroup between $\Gamma_1(p)$ and $\Gamma_0(p)$. In this article, we give an explicit basis for the group of modular units on $X(\Gamma)$ that have divisors defined over $\mathbb{Q}$.

The first example of a torsion-free abelian group $(A,+,0)$ such that the quotient group of $A$ modulo the square subgroup is not a nil-group is indicated (for both associative and general rings).

Mod p and torsion homology growth in nonpositive curvature
Inventiones Mathematicae, 2020We compute the mod p homology growth of residual sequences of finite index normal subgroups of right-angled Artin groups. We find examples where this differs from the rational homology growth, which implies the homology of subgroups in the sequence has ...

Torsion Subgroups of Incidence Algebras
Communications in Algebra, 2006Certain torsion subgroups of the incidence algebra are shown to be Abelian. If the underlying partially ordered set is finite, it is shown that there is a matrix within the incidence algebra which simultaneously diagonalizes each element of such a subgroup.

Torsion-free groups with all subgroups subnormal
Archiv der Mathematik, 2001ABSTRACT Let G be a torsion-free group with all subgroups subnormal of defect at most 4. We show that G is nilpotent of class at most 4.
