Some results about (+) proved by iterated forcing
We shall show that the consistency of CH+¬(+) and CH+(+)+there are no club guessing sequences on ω1. We shall also prove that ♢ does not imply the existence of a strong club guessing sequence on ω1. §0. Introduction. The principle (+) and its variations were first considered by the second author in [2]. They are very weak club guessing principles. The properties of the principles were largely u...

متن کاملSome Properties of Linear Logic Proved by Semantic Methods
We construct several simple algebraic models of the multiplicative and multi-plicative-additive fragments of linear logic and demonstrate the value of such models by proving some unexpected proof-theoretical properties of these fragments .
متن کاملOn Some Eigenvector-Eigenvalue Relations
This paper generalizes the well-known identity which relates the last components of the eigenvectors of a symmetric matrix A to the eigenvalues of A and of the matrix An−1, obtained by deleting the last row and column of A. The generalizations relate to matrices and to Sturm–Liouville equations.
متن کاملSome unique properties of eigenvector centrality
Eigenvectors, and the related centrality measure Bonacich’s c(β), have advantages over graph-theoretic measures like degree, betweenness, and closeness centrality: they can be used in signed and valued graphs and the beta parameter in c(β) permits the calculation of power measures for a wider variety of types of exchange. Degree, betweenness, and closeness centralities are defined only for clas...
