A remark on generalized complete intersections [PDF]
We observe that an interesting method to produce non-complete intersection subvarieties, the generalized complete intersections from L. Anderson and coworkers, can be understood and made explicit by using standard Cech cohomology machinery.

On cohomologically complete intersection modules [PDF]
Let \(I\) denote an ideal of a local ring \((R,\mathfrak{m})\). A finitely generated \(R\)-module \(M\) is called cohomologically complete intersection with respect to \(I\) if \(H^i_I(M)\) vanishes for all \(i \not= \operatorname{grade} (I,M)\), where \(H^i_I(M)\) denotes the \(i\)-th local cohomology module of \(M\) with respect to \(I\). This is the

On Quasismooth Weighted Complete Intersections [PDF]
We prove two conjectures on weighted complete intersections (cf. London Mathematical Society, Lecture Note Series, 281, Cambridge University Press, 2000, 101–173) and give the complete classification of threefold weighted complete intersections in weighted projective space that are canonically or anticanonically embedded.

Heterotic line bundle models on generalized complete intersection Calabi Yau manifolds
The systematic program of heterotic line bundle model building has resulted in a wealth of standard-like models (SLM) for particle physics. In this paper, we continue this work in the setting of generalised Complete Intersection Calabi Yau (gCICY ...

Continuité des racines d’après Rabinoff
The content of this paper is a generalization of a theorem by Joseph Rabinoff: if $\mathscr{P}$ is a finite family of pointed and rational polyhedra in $N_\mathbb{R}$ such that there exists a fan in $N_\mathbb{R}$ that contains all the recession cones of

On the Stanley Depth of Powers of Monomial Ideals
In 1982, Stanley predicted a combinatorial upper bound for the depth of any finitely generated multigraded module over a polynomial ring. The predicted invariant is now called the Stanley depth. Duval et al.

Are complete intersections complete intersections?
A commutative local ring is generally defined to be a complete intersection if its completion is isomorphic to the quotient of a regular local ring by an ideal generated by a regular sequence. It has not previously been determined whether or not such a ring is necessarily itself the quotient of a regular ring by an ideal generated by a regular sequence.
