On the closed neighborhood ideal of the square of broom and double broom graphs

Anda Olteanu, Oana Olteanu

Classes of squarefree monomial ideals were intensively studied being an important connection between two main areas in mathematics: commutative algebra and combinatorics. Many alge…

On the closed neighborhood ideal of the square of the path graph

Anda Olteanu, Oana Olteanu

We consider the closed neighborhood ideal of square of the path graph and study some of its algebraic and homological invariants. We compute the height, the projective dimension an…

Line graphs of simplicial complexes

Anda Olteanu

We consider the line graph of a pure simplicial complex. We prove that, as in the case of line graphs of simple graphs, one can compute the second graded Betti number of the facet…

The line graph of a tree and its edge ideal

Anda Olteanu

We describe all the trees with the property that the corresponding edge ideal of their line graph has a linear resolution. As a consequence, we give a complete characterization of…

Edge ideals of squares of trees

Anda Olteanu

We describe all the trees with the property that the corresponding edge ideal of the square of the tree has a linear resolution. As a consequence, we give a complete characterizati…

An oversampled collocation approach of the Wave Based Method for Helmholtz problems

Daan Huybrechs, Anda-Elena Olteanu

The Wave Based Method (WBM) is a Trefftz method for the simulation of wave problems in vibroacoustics. Like other Trefftz methods, it employs a non-standard discretisation basis co…
