1. 6. Ideals and Maximal Commutative Subrings of Graded Rings

   Författare :Johan Öinert; Matematik LTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ideals; simple rings; maximal commutativity; Crossed products; graded rings;

   Sammanfattning : This thesis is mainly concerned with the intersection between ideals and (maximal commutative) subrings of graded rings. The motivation for this investigation originates in the theory of C*-crossed product algebras associated to topological dynamical systems, where connections between intersection properties of ideals and maximal commutativity of certain subalgebras are well-known.

3. 7. Residue Currents and their Annihilator Ideals

   Författare :Elizabeth Wulcan; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; residue currents; Bochner-Martinelli formula; ideals of holomorphic functions; monomial ideals; coherents sheaves; free resolutions of modules; cellular resolutions; coherents sheaves;

   Sammanfattning : This thesis presents results in multidimensional residue theory. From a generically exact complex of locally free analytic sheaves $\mathcal C$ we construct a vector valued residue current $R^\mathcal C$, which in a sense measures the exactness of $\mathcal C$. LÄS MER

   Sammanfattning : This dissertation analyzes scientific youth culture at Swedish secondary grammar schools during an era when the faith in science, technology and progress was strong. The aim is to study the production of meaning among the students and the everyday practices they were involved in. LÄS MER

5. 9. Lefschetz Properties of Monomial Ideals

   Författare :Nasrin Altafi; Mats Boij; Alicia Dickenstein; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Weak Lefschetz property; monomial ideals; group actions; almost linear resolution; Mathematics; Matematik;

   Sammanfattning : This thesis concerns the study of the Lefschetz properties of artinian monomial algebras. An artinian algebra is said to satisfy the strong Lefschetz property if multiplication by all powers of a general linear form has maximal rank in every degree. If it holds for the first power it is said to have the weak Lefschetz property (WLP). LÄS MER

7. 10. Liksom ett par nya ögon. Frithiof Holmgren och synsinnets problematik

   Författare :Jan-Eric Olsén; Avdelningen för idé- och lärdomshistoria; []
   Nyckelord :HUMANIORA; HUMANITIES; history of ideas; History of philosophy; vivisections; colour perception; colour-blindness; the visual organ; the human body; sensations; scientific ideals; industrial technology; Frithiof Holmgren; scientific instruments; physiological experiments; laboratory medicine; physiology; Filosofins historia; idéhistoria; History of science; Vetenskapshistoria;

   Sammanfattning : This study deals with research on the visual organ as pursued in experimental physiology during the latter half of the nineteenth-century. In the 1850's och 60's experimental physiology developed as a new, scientific discipline within the curriculum of western medicine. LÄS MER
