Question Session = Spørgetime The form of the Exam made precise (en præcissering af eksamensformen) Information about the exam: FINAL Scores!!! (OBS: NEW! - posted on July 03) and Solutions to selected questions
The leading character in the course is Henri L�on Lebesgue (1875-1941). He introduced the Lebesgue integral in his dissertation from 1902, and it was a seminal work. It took some time before his ideas were accepted. A quote from the correspondence between Hermite and Stieltjes from around 1890 indicates a little the squabbles shortly before. Hermite writes: 'Je me detourne avec effroi et horreur de cette plaie lamentable des fonctions qui n'ont pas de derivees'. This was in part a reaction to the discovery by Weierstrasses of a continuous function which is not differentiable in any point. Hermite could hardly have imagined that Lebesgue just 10 years later would introduce a much larger class of functions--the Lebesgue measurable functions--and by doing so would create a completely new foundation for the mathematical analysis in the 20. century. Legesgue himself describes how many of his colleagues would tease him as being ``the man with functions without derivatives''.

Man tilmelder sig kurset elektronisk på hjemmesiden https://secure.math.ku.dk/ua.
Tirsdag kl. 11-13 i aud. 4 ved Hans Plesner Jakobsen, som kan træffes på sit kontor E415, eller på telefon 35 32 06 89, eller pr. email jakobsen@math.ku.dk.
Første forelæsning er tirsdag d. 4. februar.
De to dele af eksamen varer hver præcist 90 minutter. Det er ikke muligt at overføre tid fra den ene del til den anden.
July 03 2003: Here are the final grades: DVI-fil - postscript-fil - PDF-fil.
Here are solutions to a few of the questions on the exam: DVI-fil -postscript-fil - PDF-fil.
The written exam consists of two parts. The first 90 minutes are without any means of help ("closed book") and during this time an Essay Problem is do be finished and handed in. Here, one typically is asked to state and prove one or several specific propositions and theorems in a central topic from the course. In the remaining 90 minutes more traditional problems are to be solved, and here all usual means of help are allowed ("open book").
The essay problem will be one of the listed 14 problems The long list. Around 1 May 2003 (this will be made more precise) I choose, by some procedure, 5 of these problems and publish these on this web page. The idea is that the actual problem will be one of the 5 on this short list.
Here it is: The short list. Notice that it is different from previous exams!
In the actual exam, the essay problem will be accompanied by some remarks aimed at leading the student in the right direction. Se Old 3MI-exams (in Danish). There will both be an English and a Danish version of the exam. The students may use either language in their solutions.
| Tid | Lokale | Instruktor | |
|---|---|---|---|
| Hold 1 | Tirsag kl. 9-11 | A107 | Morten Overgaard Hansen |
| Hold 2 | Onsdag kl. 15-17 | E-37 | Klaus K�hler Holst |
Øvelsesholdene møder første gang i uge 7.
MatLab er åbent alle hverdage kl. 10-17. Det holder til i lokale E32 (i bygningerne på den anden side af Jagtvejen; 155B i gården). Du kan her sidde og regne opgaver (lokalet kan altså bruges som læseplads). Endvidere er MatLab bemandet. Bemandingsplanen er:
Vi benytter bogen "Mål- og integralteori" af Christian Berg og T age Gutmann Madsen, som kan købes i Naturfagsbogladen. Den koster 140 kr.
Supplerende noter:
