The relative hermitian picard group

Communications in Algebra, 1995
In this note, we introduce the relative hermitian Picard group of a torsion triple. Unlike the situation in the absolute case, the modules on which this group is based are no longer finitely generated nor projective. In order to compensate for this, we need a careful study of relative flatness, as well as the introduction of new techniques originally ...

Note on seminormality and Picard groups

Kobe Journal of Mathematics, 1986
The main result is that if \(R\) is an affine domain over an algebraically closed field, and has integral closure \(R'\) with \(\mathrm{Ker}(\mathrm{Pic}(R)\to \mathrm{Pic}(R'))\) of finite rank as a module over the integers, then \(R\) is seminormal (i.e., if \(a\in R'\) with \(a^2\) and \(a^3\) in \(R\), then \(a\in R)\) and \(R\) is u-closed (i.e ...

Selmer groups and Picard groups

Commentarii mathematici Universitatis Sancti Pauli = Rikkyo Daigaku sugaku zasshi, 1997
Let \(k\) be a finite field of characteristic \(p>0\) and \(K\) be an algebraic function field of one variable over \(k\). Consider an elliptic curve \(E\) over \(K\) with \(j\)-invariant transcendental over \(\mathbb{F}_p\). In this paper the author proves that there exists a finite set of primes \(S\), with \(p\in S\), such that for every positive ...

Picard Groups of Rings of Coinvariants

Algebras and Representation Theory, 2007
The author extends results of \textit{A. R. Magid} [J. Pure Appl. Algebra 17, 305-311 (1980; Zbl 0437.14002)] on the Picard group of rings of invariants. He considers Doi-Hopf data \((H,A,C)\) satisfying certain conditions that entail that \(A\otimes C\), which is always an \(A\)-coring, is also a commutative associative algebra. \(G(A\otimes C)\), the
