Further results on permanents of Laplacian matrices of trees
Open MathematicsThe research on the permanents of graph matrices is one of the contemporary research topic in algebraic combinatorics. Brualdi and Goldwasser characterized the upper and lower bounds of permanents of Laplacian matrices of trees.

Cubic surfaces and their invariants: Some memories of Raymond Stora
Nuclear Physics B, 2016 Cubic surfaces embedded in complex projective 3-space are a classical illustration of the use of old and new methods in algebraic geometry. Recently, they made their appearance in physics, and in particular aroused the interest of Raymond Stora, to the ...

Some applications of algebra to combinatorics
Discrete Applied Mathematics, 1991 The author gives a very interesting survey of the application of algebraic methods in combinatorics, in the setting of (graded) partially ordered sets and lattices. Major themes are provided by the Sperner property, rank symmetry and rank unimodality. The algebraic methods employed range from linear algebra via group actions to Lie algebras.

CODING THEORY AND ALGEBRAIC COMBINATORICS [PDF]
, 2010 This chapter introduces and elaborates on the fruitful interplay of coding theory and algebraic combinatorics, with most of the focus on the interaction of codes with combinatorial designs, finite geometries, simple groups, sphere packings, kissing numbers, lattices, and association schemes.

Combinatorics of rooted trees and Hopf algebras [PDF]
Transactions of the American Mathematical Society, 2003 We begin by considering the graded vector space with a basis consisting of rooted trees, with grading given by the count of non-root vertices. We define two linear operators on this vector space, the growth and pruning operators, which respectively raise and lower grading; their commutator is the operator that multiplies a rooted tree by its number of ...

Binomial Cayley graphs and applications to dynamics on finite spaces [PDF]
Binomial Cayley graphs are obtained by considering the binomial coefficient of the weight function of a given Cayley graph and a natural number. We introduce these objects and study two families: one associated with symmetric groups and the other with ...
