  1. 1. Ultrasheaves

    University dissertation from Uppsala : Matematiska institutionen

    Author : Jonas Eliasson; Uppsala universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Logic; symbolic and mathematical; 03G30; 03C20; 03H05; Matematisk logik; MATHEMATICS Algebra; geometry and mathematical analysis Mathematical logic; MATEMATIK Algebra; geometri och analys Matematisk logik;

    Abstract : This thesis treats ultrasheaves, sheaves on the category of ultrafilters. In the classical theory of ultrapowers, you start with an ultrafilter and, given a structure, you construct the ultrapower of the structure over the ultrafilter. READ MORE

  2. 2. Topics on Function Spaces and Multilinear Algebra

    University dissertation from Göteborg : University of Gothenburg

    Author : Mahdi Hormozi; Göteborgs universitet.; Gothenburg University.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The present thesis consists of three different papers. Indeed, they treat two different research areas: function spaces and multilinear algebra. In paper I, a characterization of continuity of the $p$-$\Lambda$-variation function is given and Helly's selection principle for $\Lambda BV^{(p)}$ functions is established. READ MORE

  3. 3. The role and use of water in agriculture in the Western Balkans: the case of Macedonia

    University dissertation from ; Department of Economics, Swedish University of Agricultural Sciences

    Author : Jordan Hristov; Sveriges lantbruksuniversitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis examines the role and demand for water in Macedonia from an economic perspective with an emphasis on agricultural use. The first paper provides an overview of the Macedonian agricultural sector and assesses the productivity growth in the period 1999-2010. In the study period, the sector experienced an average increase in volume of 1. READ MORE

  4. 4. Real and complex Monge-Ampère equations, statistical mechanics and canonical metrics

    University dissertation from Göteborg : Chalmers tekniska högskola

    Author : Jakob Hultgren; Göteborgs universitet.; Gothenburg University.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Statistical Mechanics; Point Processes; Hessian manifolds; Kähler geometry; Optimal Transport; Canonical metrics; Complex Monge-Ampère equations; Real Monge-Ampère equations; Kähler-Einstein metrics; Point Processes; Hessian manifolds; Kähler geometry; Optimal Transport; Canonical metrics; Complex Monge-Ampère equations; Real Monge-Ampère equations; Kähler-Einstein metrics;

    Abstract : Recent decades has seen a strong trend in complex geometry to study canonical metrics and the way they relate to geometric analysis, algebraic geometry and probability theory. This thesis consists of four papers each contributing to this field. The first paper sets up a probabilistic framework for real Monge-Ampère equations on tori. READ MORE
