  1. 1. Limit Shapes for qVolume Tilings of a Large Hexagon

    University essay from KTH/Matematik (Avd.)

    Author : Bako Ahmed; [2020]
    Keywords : Combinatorics; graph theory; orthogonal polynomials; Matematik; kombinatorik; grafteori; ortogonala polynom;

    Abstract : Lozenges are polygons constructed by gluing two equilateral triangles along an edge. We can fit lozenge pieces together to form larger polygons and given an appropriate polygon we can tile it with lozenges. Lozenge tilings of the semi-regular hexagon with sides A,B,C can be viewed as the 2D picture of a stack of cubes in a A x B x C box. READ MORE

  3. 2. Discrepancy of sequences and error estimates for the quasi-Monte Carlo method

    University essay from Karlstads universitet

    Author : Niklas Vesterinen; [2020]
    Keywords : discrepancy; low discrepancy sequences; van der Corput; quasi-Monte Carlo; Koksma inequality; error estimates; diskrepans; lågdiskrepanstalföljder; van der Corput; kvasi-Monte Carlo; Koksmas olikhet; feluppskattningar;

    Abstract : We present the notions of uniform distribution and discrepancy of sequences contained in the unit interval, as well as an important application of discrepancy in numerical integration by way of the quasi-Monte Carlo method. Some fundamental (and other interesting) results with regards to these notions are presented, along with some detalied and instructive examples and comparisons (some of which not often provided by the literature).

  4. 3. Photometry of carbon star wind-modelsat solar & sub-solar metallicities

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Vlad Rastau; [2020]
    Keywords : C-type AGB; photometry; mass-loss;

    Abstract : Asymptotic giant branch stars (AGB) are cool, luminous stars withan initial mass of approximately 0.8 to 8 solar masses. Towards theend of their lives they undergo heavy mass loss, a process thoughtto be caused by dust-driven winds. When it comes to carbon-richAGB stars, i. READ MORE

  5. 4. Pulsation Properties in Asymptotic Giant Branch Stars

    University essay from Uppsala universitet/Teoretisk astrofysik

    Author : Ofelia Norgren; [2019]
    Keywords : Astronomy; Asymptotic Giant Branch stars; Stellar Evolution; Variable Stars; Power Spectrum;

    Abstract : Asymptotic Giant Branch (AGB) stars are stars with low- to intermediate mass in a late stage in their stellar evolution. An important feature of stellar evolution is the ongoing nucleosynthesis, the creation of heavier elements. READ MORE

  6. 5. Limiting Behavior of the Largest Eigenvalues of Random Toeplitz Matrices

    University essay from KTH/Matematik (Inst.)

    Author : Samuel Modée; [2019]
    Keywords : Random matrix; Toeplitz matrix; largest eigenvalues; eigenvectors; slumpmatriser; Toeplitz matrices; största egenvärde; egenvektorer;

    Abstract : We consider random symmetric Toeplitz matrices of size n. Assuming that the entries on the diagonals are independent centered random variables with finite γ-th moment (γ>2), a law of large numbers is established for the largest eigenvalue. READ MORE
