On Brouwer's conjecture for the sum of k largest Laplacian eigenvalues of graphs
Let G be a simple graph with n vertices. For 1 ≤ k ≤ n , denote by S k ( G ) the sum of k largest Laplacian eigenvalues of G. It is conjectured by Brouwer that S k ( G ) ≤ e ( G ) + ( k + 1 2 ) , where e ( G ) is the number of edges in G. This conjecture

Leo Brouwer: 80 años sublimando el lenguaje guitarrístico
Leo Brouwer, el guitarrista, el compositor, el teórico que une los extremos de los diversos estilos musicales en un continuum sabio y vital. A seguir, mostraremos una conversación en la que el músico cubano da muestra de su sofisticado pensamiento ...

We explore the relationship between Brouwer's intuitionistic mathematics and Euclidean geometry. Brouwer wrote a paper in 1949 called "The contradictority of elementary geometry".

Spectral threshold dominance, Brouwer's conjecture and maximality of Laplacian energy [PDF]
The Laplacian energy of a graph is the sum of the distances of the eigenvalues of the Laplacian matrix of the graph to the graph's average degree. The maximum Laplacian energy over all graphs on n nodes and m edges is conjectured to be attained for ...

Brouwer's fixed-point theorem in real-cohesive homotopy type theory [PDF]
We combine homotopy type theory with axiomatic cohesion, expressing the latter internally with a version of ‘adjoint logic’ in which the discretization and codiscretization modalities are characterized using a judgemental formalism of ‘crisp variables ...

Implementing Brouwer’s database of strongly regular graphs [PDF]
Andries Brouwer maintains a public database of existence results for strongly regular graphs on $$n\le 1300$$n≤1300 vertices. We have implemented most of the infinite families of graphs listed there in the open-source software Sagemath (The Sage ...

Higher order functions and Brouwer’s thesis [PDF]
Extending Martín Escardó’s effectful forcing technique, we give a new proof of a well-known result: Brouwer’s monotone bar theorem holds for any bar that can be realized by a functional of type (ℕ→ℕ)→ℕ in Gödel’s System T.
