  1. 11. Traces of Mathematical Facts and Students’ Understanding of the Concept `Quadrilateral´ : An enquiry into young students’ communication

    Författare :Eva Juhlin; Maria Johansson; Ewa Bergqvist; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mathematics Education; Matematik och lärande;

    Sammanfattning : Mathematics could be described as a special kind of language, a discourse in which participants communicate abstract concepts. Communication and language are known to be important factors in teaching and learning but little is known about neither communication between students in relation to geometrical concepts, nor what traces of mathematical facts and understanding is incorporated into their communication.

  3. 12. Algorithms for Costly Global Optimization

    Författare :Nils-Hassan Quttineh; Kenneth Holmström; Hans Bruun Nielsen; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimization; systems theory; Optimeringslära; systemteori; Mathematics Applied Mathematics; Matematik tillämpad matematik;

    Sammanfattning : There exists many applications with so-called costly problems, which means that the objective function you want to maximize or minimize cannot be described using standard functions and expressions. Instead one considers these objective functions as ``black box'' where the parameter values are sent in and a function value is returned. LÄS MER

  4. 13. Tankeform och problemmiljö : skolan som kontext för tänkande i elementär matematik

    Författare :Jan Wyndhamn; Roger Säljö; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Matematikundervisning; Inlärning. Elever; Problemlösning; Matematik; Mellanstadiet;

    Sammanfattning : Avhandlingen är en sammanfattning av två empiriska studier som analyserar karaktären av kognitiva aktiviteter vid de betingelser för kommunikation som är utmärkande för pedagogiska miljöer. Elever i årskurs 6 har under vanliga matematiklektioner fått lösa vissa räkneuppgifter under olika situationella krav. LÄS MER

  5. 14. Construction of Representations of Commutation Relations by Linear Operators in Banach Spaces

    Författare :Domingos Djinja; Sergei Silvestrov; Samuel Lopes; Mälardalens universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Sammanfattning : This thesis is devoted to the construction and investigation of some properties of pairs of linear operators (A, B) (representations) satisfying commutation relations AB=BF(A), where F denotes certain polynomial. Commutation relations of this kind are called "covariance type" and finding their representations is equivalent to solving operator equations. LÄS MER

  7. 15. Asymptotics of implied volatility in the Gatheral double stochastic volatility model

    Författare :Mohammed Albuhayri; Anatoliy Malyarenko; Sergei Silvestrov; Ying Ni; Christopher Engström; Yulia Mishura; Mälardalens universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Sammanfattning : We consider a market model of financial engineering with three factors represented by three correlated Brownian motions. The volatility of the risky asset in this model is the sum of two stochastic volatilities. The dynamic of each volatility is governed by a mean-reverting process. LÄS MER
