Geometric tree graphs of points in convex position
(1999)Given a set P of points in the plane, the geometric tree graph of P is defined as the graph T(P) whose vertices are ...

Triangle-Free Planar Graphs as Segments Intersection Graphs
(1999)We prove that every triangle-free planar graph is the graph of intersection of a set of segments in the plane. Moreover, ...

3-filiform Lie algebras of dimension 8
(L'université Blaise Pascal, 1999)We give, up to isomorphism and in dimension 8, all the 3-filiform Lie algebras (whose Goze’s invariant is (n - 3,1,1,1))..

A combinatorial method for computing Steenrod squares
(Elsevier, 1999)We present here a combinatorial method for computing Steenrod squares of a simplicial set X. This method is essentially ...

On p-minimal homological models of twisted tensor products of elementary complexes localised over a prime
(American Mathematical Society, 1999)In this paper, working over Z(p) and using algebra perturbation results from [18], p-minimal homological models of twisted ...

A class of nilpotent lie algebras
(Taylor and Francis, 2000)A p-filiform Lie algebra g is a nilpotent Lie algebra for which Goze’s invariant is (n–p,1,…,1). These Lie algebras are ...

On some D-modules in dimension 2
(Cornell University, 2000)We prove a duality formula for two D-modules arising from logarithmic derivations w.r.t. a plane curve. As an application we give a differential proof of a logarithmic comparison theorem in [4].

The Size of a Graph Without Topological Complete Subgraphs
(2000)In this note we show a new upperbound for the function ex(n;TKp), i.e., the maximum number of edges of a graph of order n ...
