HIGHER-LEVEL CANONICAL SUBGROUPS FOR p-DIVISIBLE GROUPS
Let R be a complete rank-1 valuation ring of mixed characteristic (0, p), and let K be its field of fractions. A g-dimensional truncated Barsotti-Tate group G of level n over R is said to have a level-n canonical subgroup if there is a K-subgroup of G ⊗R K with geometric structure (Z/pZ) consisting of points “closest to zero”. We give a nontrivial condition on the Hasse invariant of G that guar...
متن کاملNumbers Divisible by a Large Shifted Prime and Large Torsion Subgroups of Cm Elliptic Curves
We sharpen a 1980 theorem of Erdős and Wagstaff on the distribution of positive integers having a large shifted prime divisor. Specifically, we obtain precise estimates for the quantity N(x, y) := #{n ≤ x : `− 1 | n for some `− 1 > y, ` prime}, in essentially the full range of x and y. We then present an application to a problem in arithmetic statistics. Let TCM(d) denote the largest order of a...
متن کاملNormal Subgroups of Triply Transitive Permutation Groups of Degree Divisible by 3
This result has been refined considerably by a number of authors. Wietandt and Huppert [14] introduced the notion of multiple primitivity and (t+ 89 transitivity. Wagner [13] showed that H is in fact t-fold transitive if n t is an even number and t > 3, and Saxl [8] proved that this is also true if t > 4 and n < 106. The only known examples of triply transitive groups with only doubly transitiv...
متن کاملOn the norm of the derived subgroups of all subgroups of a finite group
In this paper, we give a complete proof of Theorem 4.1(ii) and a new elementary proof of Theorem 4.1(i) in [Li and Shen, On the intersection of the normalizers of the derived subgroups of all subgroups of a finite group, J. Algebra, 323 (2010) 1349--1357]. In addition, we also give a generalization of Baer's Theorem.
متن کاملDivisible E-Cash Systems Can Be Truly Anonymous
This paper presents an off-line divisible e-cash scheme where a user can withdraw a divisible coin of monetary value 2 that he can parceled and spend anonymously and unlinkably. We present the construction of a security tag that allows to protect the anonymity of honest users and to revoke anonymity only in case of cheat for protocols based on a binary tree structure without using a trusted thi...
