EXAMENSARBETE I MATEMATIK
ALGEBRA OCH GEOMETRI



EXAMENSARBETEN: Below we proudly list the students at KTH who have finished their Examensarbete within our group. In addition to the names of the students you will find the title, a short description, the examination year and the supervisor. Note that many of our students decide to continue their studies in mathematics and become graduate students.


Dan Petersen : " Equivariant point counts of involutional hyperelliptic curves"
  • (2008/Faber).
  • Graduate student at KTH
  • Oscar Forsmann : "The Hilbert scheme of points on the projective line"
  • In this project we study in detail how the Hilbert scheme of points on the affine line glues to form the Hilbert scheme of points on the projective line (2007/Skjelnes).
  • Graduate student at KTH
  • Sara Bladh : "An approach to determinants via structure theorems "
  • We consider an alternative definition of the determinant of a linear map (2007/Laksov).
  • Andreas Holmström : "Harmonic analysis on number fields "
  • (2005/Faber).
  • David Eklund : "The second fundamental form of a family of surfaces in projective 3-space "
  • In this project the rank of the second fundamental form of a particular family of surfaces in three dimensional projective space is studied (2005/DiRocco).
  • Graduate student at KTH
  • Jonas Kiessling : "Cellularity of chain complexes"
  • We classify cellular classes of chain complexes over artinian local rings whose maximal ideal is principal and of order two (2005/Chacholski).
  • Graduate student at KTH
  • Anton Appelgren : "On certain maps of invariant rings"
  • In geometry a canonical map of invariant rings play an interesting role, and in this project we study the algebraic properties of these maps (2004/Skjelnes).
  • Christian Lundkvist : "Hilbert's Nullstellensatz and generalizations "
  • Different versions of Hilbert's Nullstellensatz is considered in this project, in particular versions applicable for not finitely generated algebras (2004/Laksov).
  • Graduate student at KTH
  • Oscar Axmon : "Determinant of an endomorphism"
  • The determinant we are familiar with, and in this project we study different approaches to define this important multilinear function (2004/Skjelnes).
  • Christian Grundh : "Calculating Fourier coefficients of vector valued Siegel modular forms and traces of Hecke operators "
  • (2003/Faber).
  • Graduate student at KTH
  • Johanna Nilsson : "Solutions to pXY+qYX=1 over an arbitrary field "
  • The solutions of the equation pXY+qYX=1 as square matrices over algebraically closed fields of characteristic different from two are found. This is a continuation of the Master's thesis "Equations over matrix rings" by John Andersson (2003/Boij).
  • Graduate student at KTH
  • Dan Sjöstrand : "Cayley-Hamilton theorem"
  • In this project we consider several of the many different proofs of the famous Cayley-Hamilton theorem (2003/Laksov).
  • Fredrik Nordström : "Recovering a module from its local structure"
  • In this project we study what information is needed to rebuild the module from only knowing the information about the stalks around each prime ideal (2003/Skjelnes).
  • Graduate student at KTH
  • David Rydh : "Chow varieties"
  • The Chow scheme of cycles on projective varieties is considered in this project (2003/Laksov).
  • Graduate student at KTH
  • John Andersson : "Equations over matrix rings"
  • The solutions of quadratic equations in square matrices over an algebraically closed field of characteristic zero are described and classified (2002/Boij).
  • Graduate student at KTH
  • Jonas Bergström : "Curves of genus three over finite fields"
  • (2001/Faber).
  • Graduate student at KTH
  • Jonas Söderberg : "Normal forms for matrices"
  • An alternative normal forms for matrices has been suggested which would give the space of square matrices a nice cell decomposition. This kind of normal forms is studied and proved not to exist in the case of four by four matrices (2001/Boij).
  • Graduate student at KTH
  • Magnus Hessel : "Weyl groups of matrix groups"
  • The theory of Weyl groups is presented in a purely algebraic manner and some of the aspects of positive characteristic is considered (1998/Boij).
  • Erik Norhammar : "Groups, rings and fields"
  • Here the fundamental algebraic objects are introduced with a didactic point of view (1997/Laksov).
  • Fredrik Andreasson : "Nullstellen theorems"
  • Several Nullstellen theorems and proofs are considered, and in particular versions that hold over non-closed fields (1995/Laksov).
  • Graduate student at KTH
  • Mats Boij : "Modified Linear Recurrence Sequences "
  • (1990/Laksov).
  • Graduate student at KTH
  • Lars Ernström : " "
  • (1989/Laksov).
  • Graduate student at KTH/MIT
  • Karin Westin : ""
  • Versions of the Nullstellen theorems over non-algebraically closed fields are considered (19xx/Laksov).
