On non-commutative Iwasawa theory and derivatives of Euler systems
David Burns, Takamichi Sano
We use the theory of reduced determinant functors from [24] to give a new, computationally useful, description of the relative -groups of orders in finite dimensional separabl…

On non-commutative Euler systems, I: preliminaries on `det' and `Fit'
David Burns, Takamichi Sano
We extend some classical constructions in commutative algebra to the setting of modules over orders in (non-commutative) semisimple algebras. Our theory incorporates, inter alia, `…

On a refinement of the Birch and Swinnerton-Dyer Conjecture in positive characteristic
David Burns, Mahesh Kakde, Wansu Kim
We formulate a refined version of the Birch and Swinnerton-Dyer conjecture for abelian varieties over global function fields. This refinement incorporates both families of congruen…
