Preface to the Series
TheNielsHenrikAbelMemorialFundwasestablishedbytheNorwegiangov-
ernmentonJanuary1,2002.ThemainobjectiveistohonorthegreatNorwe-
gian mathematician Niels Henrik Abel by awarding an international prize for
outstanding scientific work in the field of mathematics. The prize shall con-
tributetowardsraisingthestatusofmathematicsinsocietyandstimulatethe
interest for science among school children and students. In keeping with this
objective the board of the Abel fund has decided to finance one or two Abel
Symposia each year. The topic may be selected broadly in the area of pure
and applied mathematics. The Symposia should be at the highest interna-
tionallevel,andservetobuildbridgesbetweenthenationalandinternational
researchcommunities.TheNorwegianMathematicalSocietyisresponsiblefor
the events. It has also been decided that the contributions from these Sym-
posia should be presented in a series of proceedings, and Springer Verlag has
enthusiastically agreed to publish the series. The board of the Niels Henrik
AbelMemorialFundisconfidentthattheserieswillbeavaluablecontribution
to the mathematical literature.

Preface
Kiyosi Itoˆ, the founder of stochastic calculus, is one of the few central figures
of the twentieth century mathematics who reshaped the mathematical world.
Today stochastic calculus, also called Itˆo calculus, is a central research field
in mathematics, with branches to several other mathematical disciplines and
with many areas of application, for example physics, engineering and biology.
Perhapsthemostspectacularfieldofapplicationsatpresentiseconomicsand
finance.Indeed,theNobelPrizeinEconomicsin1997wasawardedtoRobert
MertonandMyronScholesfortheirderivationofthecelebratedBlack–Scholes
option pricing formula using stochastic calculus.
The Abel Symposium 2005 took place in Oslo, July 29th – August 4th
2005, and was organized as a tribute to Kiyosi Itoˆ and his works on the
occasion of his 90th birthday.
Distinguished researchers from all over the world were invited to present
thenewestdevelopmentswithintheexcitingandfastgrowingfieldofstochas-
tic calculus. We were happy that so many took part to this event. They were,

In addition there were many other international experts both attending
and presenting valuable contributions to the conference. We are grateful to
all for making this symposium so successful.
The present volume combines both papers from the invited speakers and
contributions by the presenting lecturers. We are happy that so many sent
their papers for publication in this proceedings, making it a valuable account
of the research frontiers in stochastic analysis. Our gratitude is also directed
to all the referees that put time and effort in reading the manuscripts.
A special feature of this volume is given by the Memoirs that Kiyosi Itoˆ
himself wrote for this occasion. We all thank him for these valuable pages
which mean so much to both young and established researchers in the field.
WealsothanktheAbelFoundation,throughtheNorwegianMathematical
Society,andtheCentreofMathematicsforApplications(CMA)attheUniver-
sityofOslo,fortheirfinancialsupportandfortheirhelpwiththepreparation
andorganizationofthesymposium.OurspecialthanksgotoIngaB˚ardshaug
Eide and Helge Galdal for their help with all practical matters before and
during the conference.
Last but not least we are indebted to Sergio Albeverio for his scientific
advice in the organization of the program.
