1. 1. A Study of Smooth Functions and Differential Equations on Fractals

   Författare :Anders Pelander; Anders Öberg; Svante Janson; Alexander Teplyaev; Tom Lindström; Uppsala universitet; []
   Nyckelord :Mathematical analysis; Analysis on fractals; p.c.f. fractals; Sierpinski gasket; Laplacian; differential equations on fractals; infinite dimensional i.f.s.; invariant measure; harmonic functions; smooth functions; derivatives; products of random matrices; Matematisk analys;

   Sammanfattning : In 1989 Jun Kigami made an analytic construction of a Laplacian on the Sierpiński gasket, a construction that he extended to post critically finite fractals. Since then, this field has evolved into a proper theory of analysis on fractals. The new results obtained in this thesis are all in the setting of Kigami's theory. LÄS MER

3. 2. Transcriptome analysis on in vivo derived laser microbeam microdissected cells. Analysis of smooth muscle transcriptomes

   Författare :Stefan Johannes Scheidl; Göteborgs universitet; []
   Nyckelord :microarray; laser microdissection; RNA amplification; smooth muscle cells; smooth muscle differentiation; smooth muscle transcriptome; smooth muscle diversity;

   Sammanfattning : Smooth muscle cells (SMCs) are found in the respiratory, urogenital, circulatory and digestive systems. They provide contractility and structural support for those organs and perform multiple physiological important functions, such as modulation of blood pressure, regulation of airway resistance, and control of gastrointestinal and genitourinary motility.

4. 3. Regulation of the vascular smooth muscle cell phenotype

   Författare :Henrik Lindskog; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiogenesis; embryonic stem cells; vascular smooth muscle cell; smooth muscle cell; pericyte; phenotypic modulation; lipoma preferred partner; ectra-cellular matrix; zinc finger protein 148;

   Sammanfattning : Smooth muscle cells (SMC) are present in many internal organs such as the blood vessels and the gastrointestinal channel. Their main functions are to provide stability to the tissue and to provide contractile capability. SMC are not terminally differentiated but can switch between several phenotypes, which is also known as phenotypic modulation. LÄS MER

5. 4. The Maximum Principle for Cauchy-Riemann Functions and Hypocomplexity

   Författare :Abtin Daghighi; Stefan Borell; Christer Kiselman; Egmont Porten; Juergen Leiterer; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hypocomplexity; hypoanalytic structure; CR functions; maximum principle; weak pseudoconcavity;

   Sammanfattning : This licentiate thesis contains results on the maximum principle forCauchy–Riemann functions (CR functions) on weakly 1-concave CRmanifolds and hypocomplexity of locally integrable structures. Themaximum principle does not hold true in general for smooth CR functions,and basic counterexamples can be constructed in the presenceof strictly pseudoconvex points. LÄS MER

7. 5. Invariant Subspaces in Spaces of Analytic Functions

   Författare :Ali Abkar; Matematik (naturvetenskapliga fakulteten); []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; functional analysis; Series; Fourier analysis; weighted Bergman space.; super-biharmonic function; quasi-Banach space of analytic functions; index; multiplier module homomorphism; multiplier; Banach space of analytic functions; hyperinvariant subspace; Serier; fourieranalys; funktionsanalys;

   Sammanfattning : Let D be a finitely connected bounded domain with smooth boundary in the complex plane. We first study Banach spaces of analytic functions on D . The main result is a theorem which converts the study of hyperinvariant subspaces on multiply connected domains into the study of hyperinvariant subspaces on domains with fewer holes. LÄS MER
