Boundary Value Problems in Elasticity and Thermoelasticity
… dissertation the author solves a series of mixed boundary value problems arising from crack problems in elasticity and thermoelasticity. Using integral transform techniques and separation of variables appropriately, it is shown that the solutions can be found by solving a corresponding set of …

Coefficient recovery in parabolic initial boundary value problems
… equations with specified initial and boundary conditions. We primarily explore the recovery of the diffusivity coefficient in the heat equation using a very limited amount of data on a portion of the spatial boundary. In the process, we show that the coefficient dependent observation …

Boundary Value Problems Of Spaces Of Automorphic Forms
We apply some ideas of Bombieri and Garrett to construct natural self-adjoint operators on spaces of automorphic forms whose only possible discrete spectrum is λ s = s(s − 1) for s in a subset of on-line zeros of an L-function, appearing as a compact period of cuspidal-data Eisenstein series on GL …

Boundary Value Problems in Rectilinearly Anisotropic Thermoelastic Solids
<p>The boundary value problems which are considered are the type that arise due to the presence of a Griffith crack (or cracks) in an anisotropic thermoelastic solid. The thermoelastic field, in such materials, when the infinitesimal theory is employed, is governed by a set of elliptic partial …

Boundary-value problems for transversely isotropic hyperelastic solids
In this thesis we examine three boundary-value problems combined with the presence of dead-load tractions in respect of transersely isotropic elastic materials. In particular, Chapter 1 mainly consists of existing preliminary remarks on the continuum (phenomenological) approach used here to study …

Theory of multidimensional Laplace transforms and boundary value problems
… two dimensional Laplace transforms. Last, some boundary value problems characterized by linear partial differential equations involving heat and wave equations are explicitly solved by using the obtained results to illustrate the applications.</p>

Degree Theory and Nonlinear Boundary Value Problems at Resonance
… solutions of ${\cal L}y$ = f satisfying linear boundary conditions on (a,b). The function f is an element of $L\sp1$ (a,b) Define BC = $\{y \in L\sp\infty$ (a,b): $y\sp\prime$ is absolutely continuous on (a,b), and y satisfies the boundary conditions$\}$. Assume the null space of L:BC $\to$ …

Boundary data smoothness for solutions of nonlocal boundary value problems.
In this dissertation, we investigate boundary data smoothness for solutions of nonlocal boundary value problems over discrete and continuous domains. Essentially, we show that under certain conditions partial derivatives and differences exist, with respect to boundary conditions, for solutions of …

A functional approach to positive solutions of boundary value problems.
… second, third, fourth, and nth order families of boundary value problems. We begin by characterizing second order problems having left and right focal boundary conditions. Via an appropriate substitution, associated third, fourth, and nth order problems are resolved. Our main result centers on the …

Some composite boundary value problems in electromagnetics and their applications
In this thesis, some composite boundary value problems of stratified media with various types of discontinuities are discussed. These problems fall into three categories: (i) a disk on top of a stratified medium; (ii) a general multiregion vertically stratified medium; and (iii) a slantingly …
