[HTML][HTML] Riemann–Roch like theorem for triangulated categories

I Mori - Journal of Pure and Applied Algebra, 2004 - Elsevier
We will prove a Riemann–Roch like theorem for triangulated categories satisfying Serre
duality. As an application, we will prove Riemann–Roch Theorem and Adjunction Formula …

Cubist algebras

J Chuang, W Turner - Advances in Mathematics, 2008 - Elsevier
We construct algebras from rhombohedral tilings of Euclidean space obtained as projections
of certain cubical complexes. We show that these 'Cubist algebras' satisfy strong …

Symmetry in the vanishing of Ext over stably symmetric algebras

I Mori - Journal of Algebra, 2007 - Elsevier
A Frobenius algebra over a field k is called symmetric if the Nakayama automorphism is an
inner automorphism. A stably symmetric algebra is defined to be a generalization of a …

Co-point modules over Frobenius Koszul algebras

I Mori - Communications in Algebra®, 2008 - Taylor & Francis
Let A be a Frobenius Koszul algebra such that its Koszul dual A! is a quantum polynomial
algebra. Co-point modules over A were defined as dual notion of point modules over A! with …

Stable projective homotopy theory of modules, tails, and Koszul duality

RM Villa, A Martsinkovsky - Communications in Algebra®, 2010 - Taylor & Francis
A contravariant functor is constructed from the stable projective homotopy theory of finitely
generated graded modules over a finite-dimensional algebra to the derived category of its …

Asymmetry of Ext-groups

I Mori - Journal of Algebra, 2009 - Elsevier
In this paper, we will use techniques of noncommutative projective geometry to construct
examples of algebras R over a field k not satisfying the following two types of symmetric …

[PDF][PDF] Homogeneous G-algebras I

R Martınez-Villa, J Mondragón - International Journal of Algebra, 2014 - m-hikari.com
This is the first of a pair of papers on homogeneous G-algebras. G-algebras, or Groebner
basis algebras, were studied by Levandosky, generalizing results by Apel and Berger. We …

On tea, donuts and non-commutative geometry

I Nikolaev - arXiv preprint arXiv:1605.07543, 2016 - arxiv.org
As many will agree, it feels good to complement a cup of tea by a donut or two. This sweet
relationship is also a guiding principle of non-commutative geometry known as Serre …

[PDF][PDF] SERRE DUALITY FOR NONCOMMUTATIVE ALGEBRAS

I MORI - mathsoc.jp
One of the major projects in noncommutative algebraic geometry is to classify
noncommutative curves and noncommutative surfaces [17]. The first half of this article will …

[PDF][PDF] Cohomology of tails and stable cohomology over Koszul quiver algebras

RM Villa, A Martsinkovsky - researchgate.net
The main result of this announcement shows that, under Koszul duality between quiver
algebras, cohomology of tails is naturally isomorphic to stable cohomology. As an …
