    Vincular and covincular patterns are generalizations of classical patterns allowing restrictions on the indices and values of the occurrences in a permutation. In this paper we study the integer sequences arising as the enumerations of permutations ...

    stærðfræðinámi er mikilvægt að huga að uppbyggingu hugtakaskilnings. Góð leið til þess er að rannsaka og prófa hugtök með áþreifanlegum verkefnum og tilraunum. Líkur er eitt af þeim hugtökum sem gott er að glöggva sig á með tilraunum. Líkum má skipta ...

    Landspróf miðskóla sem inntökupróf í menntaskóla og kennaraskóla og síðar fleiri skóla var haldið á árunum 1946–1976. Prófað var í átta námsgreinum þar sem íslenska vó tvöfalt. Landsprófið var upphaflega grundvallað á reglugerð nr. 3/1937 um námsefni ...

    Athugun á niðurstöðum í stærðfræði í PISA-rannsókninni 2003 sýndi að árangur nemenda í tveimur stærstu skólunum var marktækt betri en í minni skólum. Sérstaklega var árangurinn slakur í skólum með 11–25 þátttakendur. Athugun á árangri í dönskum skólum ...

    The first main theme of this thesis is the approximation of holomorphic functions on Stein manifolds by polynomials. In our setting a polynomial is an entire function whose absolute value is bounded from above by $\exp(a\psi+b)$ on the complement of a ...
  • Guðmundsson, Skúli; Hafstein, Sigurdur (Hindawi Limited, 2018)
    We study stability for dynamical systems specifed by autonomous stochastic diferential equations of the form dX(t) = f(X(t))dt + g(X(t))dW(t), with (X(t))t≥0 an Rd -valued Ito process and ˆ (W(t))t≥0 an RQ-valued Wiener process, and the functions f ...
