Examiner and lecturer

Hjalmar Rosengren

G. B. Folland: Fourier analysis and its applications, Wadsworth & Brooks/Cole, 1992.
Folland's book will be sold by UBS after the first lecture September 3, 15.00. The price of the book is 500 SEK.
Further material

M. Asadzadeh, Lecture notes in Fourier analysis, in preparation.
We will use these notes for the chapter on Laplace transform, and they can also be useful for supplementary reading.
A ps-file is available here, but since there may be changes, do not print it all at once (Chapter 1 is enough for a start).
Notes 1 on Laplace transform.
Notes 2 on Bessel's inequality.
Notes 3 on the Gibbs phenomenon and periodic solutions to ODE.
Notes 4 on L2 theory of Fourier series.
Notes 5 on filters.
Corrections to Folland's book.
Some additional problems in Swedish and English. These exercises do not reflect the course content precisely.
Course contents and theory check-list.
Additional material may become available later.

Tag med giltig legitimation och kvitto på erlagd kåravgift!
Meddelande om resultat fås med epost via LADOK. (Detta sker automatiskt så fort tentan är rättad och resultaten är registrerade.)
Rättade tentor återfås på expeditionen för matematik.
Kontrollera att Du har fått rätt betyg och att poängsumman stämmer.
Eventuella klagomål på rättningen ska lämnas skriftligt (på expeditionen finns en blankett till hjälp).
