Planteamiento e interpretación de problemas contextualizados de extremos

Según Polya (1962), la principal finalidad de las matemáticas del currículum de secundaria es enseñar a los alumnos a PENSAR. Este "pensar" lo identificamos, al menos en una primera aproximación, con "la resolución de problemas”, considerada de suma importancia en el currículum de matemáticas de nuestro país (Departament d’Educació, 2008). Además de una herramienta para aprender a “pensar matemáticamente”, la resolución de problemas la consideramos, en sí misma, como un método de enseñanza: es la interacción con situaciones problemáticas la que hace que los alumnos construyan activamente su conocimiento (Vila y Callejo, 2004; Onrubia y otros, 2001)

Didàctica de la resolució de problemes per al desenvolupament de la competència matemàtica

Els problemes són un mitjà per posar l’èmfasi en els alumnes, en els seus processos de pensament i en els mètodes inquisitius; una eina per formar subjectes amb capacitat autònoma de resoldre problemes, crítics i reflexius, capaços de preguntar-se pels fets. Es convenient seleccionar problemes que siguin accessibles als alumnes però que al mateix temps els suposi un repte, encoratjant l’exposició d’idees, l’argumentació i l’esperit crític. Han de fomentar el treball en grup entre els estudiants, la comunicació d’idees, el contrast i el diàleg. Han d’interessar als estudiants en processos generadors de coneixement com definir, fer-se preguntes i preguntar, observar, classificar, particularitzar, generalitzar, conjecturar, demostrar i aplicar

Linear algebra: selected problems

Linear Algebra—Selected Problems is a unique book for senior undergraduate and graduate students to fast review basic materials in Linear Algebra. Vector spaces are presented first, and linear transformations are reviewed secondly. Matrices and Linear systems are presented. Determinants and Basic geometry are presented in the last two chapters. The solutions for proposed excises are listed for readers to references.

Some Problems In Algebra And Topology A Study Of Fuzzy Convexity With Special Reference To Separation Properties

This thesis is a study of abstract fuzzy convexity spaces and fuzzy topology fuzzy convexity spaces No attempt seems to have been made to develop a fuzzy convexity theoryin abstract situations. The purpose of this thesis is to introduce fuzzy convexity theory in abstract situations

Inverse problems in dynamic cognitive modeling

Inverse problems for dynamical system models of cognitive processes comprise the determination of synaptic weight matrices or kernel functions for neural networks or neural/dynamic field models, respectively. We introduce dynamic cognitive modeling as a three tier top-down approach where cognitive processes are first described as algorithms that operate on complex symbolic data structures. Second, symbolic expressions and operations are represented by states and transformations in abstract vector spaces. Third, prescribed trajectories through representation space are implemented in neurodynamical systems. We discuss the Amari equation for a neural/dynamic field theory as a special case and show that the kernel construction problem is particularly ill-posed. We suggest a Tikhonov-Hebbian learning method as regularization technique and demonstrate its validity and robustness for basic examples of cognitive computations.

Algebraic duality theorems for infinite LP problems

In this paper we consider a primal-dual infinite linear programming problem-pair, i.e. LPs on infinite dimensional spaces with infinitely many constraints. We present two duality theorems for the problem-pair: a weak and a strong duality theorem. We do not assume any topology on the vector spaces, therefore our results are algebraic duality theorems. As an application, we consider transferable utility cooperative games with arbitrarily many players.

Non-compact generalized variational inequalities for quasi-monotone and hemi-continuous operators with applications

Some results are obtained for non-compact cases in topological vector spaces for the existence problem of solutions for some set-valued variational inequalities with quasi-monotone and lower hemi-continuous operators, and with quasi-semi-monotone and upper hemi-continuous operators. Some applications are given in non-reflexive Banach spaces for these existence problems of solutions and for perturbation problems for these set-valued variational inequalities with quasi-monotone and quasi-semi-monotone operators.

Bayes linear spaces

Linear spaces consisting of σ-finite probability measures and infinite measures (improper priors and likelihood functions) are defined. The commutative group operation, called perturbation, is the updating given by Bayes theorem; the inverse operation is the Radon-Nikodym derivative. Bayes spaces of measures are sets of classes of proportional measures. In this framework, basic notions of mathematical statistics get a simple algebraic interpretation. For example, exponential families appear as affine subspaces with their sufficient statistics as a basis. Bayesian statistics, in particular some well-known properties of conjugated priors and likelihood functions, are revisited and slightly extended
