Different Types of Weighted Composition Operators on Banach Spaces of Analytic Functions
(Åbo Akademi - Åbo Akademi University, 26.05.2023)Many problems in real life are, at least approximatively, of linear nature and can be mathematically examined with the aid of linear spaces. It is natural to measure the size of objects occurring in the problems and such ... -
Applications of Max-Plus Algebra to Scheduling
(Åbo Akademis förlag - Åbo Akademi University Press, 12.05.2021)Max-plus algebra provides mathematical theory and techniques for solving nonlinear problems that can be given the form of linear problems, when arithmetical addition is replaced by the operation of maximum and arithmetical ... -
Hilbert matrix, Volterra and weighted composition operators on Banach spaces of analytic functions
(Åbo Akademi - Åbo Akademi University, 11.12.2020)Avsikten med denna avhandling är att studera två klassiska linjära integraloperatorer, Hilbertmatrisoperatorn H och den generaliserade Volterraoperatorn Tϕg mellan Banachrum av analytiska funktioner på den öppna enhetsdisken ... -
Hitting times in urn models and occupation times in one-dimensional diffusion models
(Åbo Akademi - Åbo Akademi University, 11.09.2020)The main subject of this thesis is certain functionals of Markov processes. The thesis can be said to consist of three parts. The first part concerns hitting times in urnmodels, which are Markov processes in discrete time. ... -
Explicit results in theory of zeros and prime numbers
(Åbo Akademi - Åbo Akademi University, 28.08.2020)This thesis is comprised of three articles in which we prove explicit estimates for different number theoretical problems.In the first article we derive an explicit Riemann-von Mangoldt formula for the Selberg class ... -

Exit times for some processes with normally distributed noise
(Åbo Akademi - Åbo Akademi University, 31.10.2014)Denna avhandling handlar om metoder för att hitta begränsningar för det asymptotiska beteendet hos en förväntad uthoppstid från ett område omkring en xpunkt för processer som har normalfördelad störning. I huvudsak behandlas ... -

The knapsack problem approach in solving partial hedging problems of options
(Åbo Akademis förlag - Åbo Akademi University Press, 31.08.2012)This thesis introduces a new approach for studying the problem of optimal partial hedging of both European and American options in a nite and complete discrete-time market model. We show how certain partial hedging problems, ... -

Boundary identification in the domain of a parabolic partial differential equation
(Åbo Akademi - Åbo Akademi University, 16.01.2009)Bakgrunden och inspirationen till föreliggande studie är tidigare forskning i tillämpningar på randidentifiering i metallindustrin. Effektiv randidentifiering möjliggör mindre säkerhetsmarginaler och längre serviceintervall ...
