The Cauchy problem for a fourth order parabolic equation by difference methods [PDF]

open access: yes, 1953
Thesis (Ph.D.)--Boston UniversityThis paper deals with the solution of parabolic partial differential equations by difference methods. It is first concerned with obtaining certain basic results for the nth order equation... This enables one to exhibit a

Chainability and Hemmingsen\u27s Theorem [PDF]

open access: yes, 2006
On the surface, the definitions of chainability and Lebesgue covering dimension ⩽1 are quite similar as covering properties. Using the ultracoproduct construction for compact Hausdorff spaces, we explore the assertion that the similarity is only skin ...

Reducibility for a class of weakly dispersive linear operators arising from the Degasperis Procesi equation

open access: yes, 2018
We prove reducibility of a class of quasi-periodically forced linear equations of the form \[ \partial_tu-\partial_x\circ (1+a(\omega t, x))u+\mathcal{Q}(\omega t)u=0,\quad x\in\mathbb{T}:=\mathbb{R}/2\pi\mathbb{Z}, \] where $u=u(t,x)$, $a$ is a small ...

Combining Theorem Proving and Model Checking in the Safety-Critical Software Development through Translating Event-B to SMV

open access: yesMATEC Web of Conferences, 2017
Model checking and theorem proving are two key vertification techniques in the formal method, but each has its advantages and disadvantages. In this paper, we first try to present the general model transformation rules from Event-B to SMV in order to ...
