This paper investigates the semantics of kind-referring expressions and of generic quantification in Brazilian Portuguese (BP). It may thus be taken as a contribution to the development of a more accurate understanding of genericity as a crosslinguistic phenomenon. In BP genericity may be expressed by both definite singular (1) and definite plural (2) nominals, and also by indefinite nominals s...

Sparse linear equations Kd r are considered, where K is a specially structured symmetric indefinite matrix that arises in numerical optimization and elsewhere. Under certain conditions, K is quasidefinite. The Cholesky factorization PKP T LDL T is then known to exist for any permutation P, even though D is indefinite. Quasidefinite matrices have been used successfully by Vanderbei within barrie...

We assume that A is n×n and C is an m×m matrix. Many such systems arise from 9 the discretization of (systems of) partial differential equations. For example, Stokes 10 equations discretized with stable finite elements or a mixed finite element method 11 for second order elliptic PDEs lead to a positive definite matrix A and to C = 0, so 12 that (1) has a genuine saddle point structure. Certain...

We present a Weyl-type relative bound for eigenvalues of Hermitian perturbations A + E of (not necessarily definite) Hermitian matrices A. This bound, given in function of the quantity η = ‖A−1/2EA−1/2‖2, that was already known in the definite case, is shown to be valid as well in the indefinite case. We also extend to the indefinite case relative eigenvector bounds which depend on the same qua...

In this paper we are interested in defining affine structures on discrete quadrangular surfaces of the affine three-space. We introduce, in a constructive way, two classes of such surfaces, called respectively indefinite and definite surfaces. The underlying meshes for indefinite surfaces are asymptotic nets satisfying a non-degeneracy condition, while the underlying meshes for definite surface...

We examine the distribution and interpretation of post-copular noun phrases in French when they appear with and without an indefinite article (Marie est (une) physicienne). We propose that the alternation is due to the fact that the indefinite article marks saturation of an NP-internal argument slot, and show that because of this, post-copular indefinite NPs are usually but not always existenti...

Asymmetric generalization patterns for definite and indefinite singular generics In two experiments, we investigated the role of grammatical form in inferring the conceptual status of properties in generic sentences. We trained participants on novel properties in pseudoword sentences with bare plural (BP), indefinite (IS) and definite singular (DS) subjects. In the test phase, participants rate...

Due to updating the Lagrangian multiplier twice at each iteration, the symmetric alternating direction method of multipliers (S-ADMM) often performs better than other ADMM-type methods. In practical applications, some proximal terms with positive definite proximal matrices are often added to its subproblems, and it is commonly known that large proximal parameter of the proximal term often resul...

Abstract Having considered the symbolic phase of a sparse Cholesky solver in previous chapter, focus this chapter is subsequent numerical factorization phase. If A symmetric positive definite (SPD) matrix, then it factorizable (strongly regular) and (in exact arithmetic) its = LL T exists. LDLT factorizations general indefinite matrices are Chapter 7 .

This paper focuses on the impact of social cognition thes processing linguistic information. More specifically, it brings some insights to Relevance theory's construal Meaning NN , which seeks account for non-propositional meanings. It shows, through two experiments, how gender and nationality-related stereotypes guide definite indefinite descriptions. Experiment 1 consists a self-paced reading...
