Research from Tensorgami

Research papers from the earlier Tensorgami programme, preserved with their versions, citations, publication details and corrections.

Refacte’s current work centres on mechanism calculi: inventing the operations that make a problem tractable. These papers belong to the earlier research programme. Their scholarly status and citations are retained; they are no longer presented as the site’s current direction.

Finite generation of permutation twisted cohomology

Representation spheres give multigraded section rings for permutation modules. This paper proves a finite-module theorem over arbitrary commutative Noetherian bases and uses the doubled regular representation to construct an explicit Noetherian model for the tensor-triangular geometry of permutation complexes.
