On Constraints Imposed by Independent Gonal Morphisms for a CurveJiang, Feiqi January 2018 (has links)
In this thesis, we explore the restrictions imposed on the genus of a smooth curve $X$ which possesses at least three independent gonal morphisms to $\Pp^1$. We will prove a sharp lower bound on the dimension of global sections given by the sum of the divisors for the gonal morphisms. This inequality will provide an upper bound on the genus of a curve with the described properties. By considering the birational image of $X$ in $\Pp^1 \times \Pp^1 \times \Pp^1$ under the product of three pairwise independent morphisms, we observe that the boundary case for the previously mentioned inequality is closely related to the case where the image of $X$ is contained in a type 1-1-1 surface. Motivated by this phenomenon, we examine the constraints on the arithmetic genus of an irreducible curve in $\Pp^1 \times \Pp^1 \times \Pp^1$ whose natural projections are pairwise independent and all have degree 7.

Rational surfaces, simple Lie algebras and flat G bundles over elliptic curves. / CUHK electronic theses & dissertations collectionJanuary 2007 (has links)
It is well-known that del Pezzo surfaces of degree 9 -- n. are in one-to-one correspondence to flat En bundles over elliptic curves which are anti-canonical curves of such surfaces. In my thesis, we study a broader class of rational surfaces which are called ADE surfaces. We construct Lie algebra bundles of any type on these surfaces, and extend the above correspondence to flat G bundles over elliptic curves, where G is a simple, compact and simply-connected Lie group of any type. Concretely, we establish a natural identification between the following two very different moduli spaces for a Lie group G of any type: the moduli space of rational surfaces with G-configurations and the moduli space of flat G-bundles over a fixed elliptic curve. / Zhang, Jiajin. / "July 2007." / Adviser: Leung Nai Chung Conan. / Source: Dissertation Abstracts International, Volume: 69-01, Section: B, page: 0357. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2007. / Includes bibliographical references (p. 77-79). / Electronic reproduction.

Computational characterization of adhesive bond properties using guided waves in bonded platesKoreck, Juergen 25 August 2006 (has links)
This research focuses on the application of guided waves techniques
to nondestructively characterize the structural integrity of bonded
engineering components. Computational methods are used to examine
the properties of multi-layered, adhesive bonded plates. This study
quantifies the effect of the adhesive bond parameters (Young's
modulus, Poisson's ration and bond thickness) on the dispersion
curves. A commercial finite element (FE) code (ABAQUS/Explicit) is
used for the numerical model while the global matrix method and the
waveguide FE method are used to benchmark the resulting dispersion
relationships in the form of a frequency-wavenumber or
slowness-frequency relation. The postprocessing of FE data includes
the two-dimensional Fourier transform (2D-FFT) and the short-time
Fourier transform (STFT). Note that the 2D-FFT and STFT operate on
multiple or just one transient output signals of the FE results
respectively, while the waveguide FE method uses mass-, damping- and
stiffness-matrices to generate the dispersion relations. In the
dispersion relations, a set of bond parameter sensitive and
FE-visible points is selected. The frequency locations of these
points represent the solution criteria for the inversion procedure
based on the global matrix method. The capabilities of the inversion
process depend on the number of transient output signals from an FE
simulation for the forward problem.
