We study a 1+1 dimensional Yang-Mills model in the light-cone gauge (the ’t Hooft model). The colour group is SU (N ) and we study the limit N → ∞, the limit is taken such that g²N is kept constant. In this limit the only contributing diagrams are planar diagrams without gluon-gluon interactions. Using this, it is shown that there are no free quarks in this model. The bound state wave equation is

Det japanska samhället är genomsyrat av socialt hierarkiska förhållanden. Bortsett från detta är det sociocentriskt betingat i det att personen är en del av helheten, snarare än att samhället består av en samling individer. Varför är det på detta sätt? Hur kommer det sig att det japanska samhället tar sig an en så pass annorlunda form i förhållande till det västerländska? Denna uppsats diskuterar
In light of the pronounced regression in total fertility rates in Spain over the last 40 years and the permanence well below replacement fertility levels up until the present day, this thesis aims to add evidence to the on-going debate about the determinants of reproductive behaviour in this specific country. Given the presence of a significant heterogeneity in the pace of changes in and levels of
Efter finanskrisen 2008 syntes en nedgång i kvinnors relativa arbetskraftstal i förhållande till mäns. En företeelse som tidigare inte observerats.

Studien undersöker närmare det generella sambandet mellan kvinnors arbetskraftsdeltagande, konjunkturläge och geografisk placering i avsikt att skilja trende
This qualitative study utilizes the so far seldom used protocols of parish councils to study the processes of investments in early primary education in 11 Swedish parishes in the southern region of Scania. The aim of the thesis is to study the reasons for investments during the period 1830 to 1850. The hypothesis is that farmers that have stronger property rights over their farmland are more likel
Throughout history, changes have occurred in the energy system, where social and economic factors have been identified as drivers for these changes. The purpose of this study is to investigate whether crises, financial crises and energy supply crises, have been drivers for changes in the energy system in Sweden for the period 1900-2013. To investigate these changes, energy prices is measured as th
Tidigare forskning är oenig om räntans effekt på bostadspriserna. Vissa menar att räntan har haft en avgörande roll i att bostadspriserna har stigit sedan mitten av 90-talet medan andra attributerar ökningen till andra makroekonomiska faktorer. I och med att räntan har sjunkit under samma period som bostadspriserna har stigit är kopplingen förståelig och lätt att göra, men är den korrekt? Syftet m
