An analytical study of a model for the actin-based movement of bacteria [PDF]

open access: yesRendiconti di Matematica e delle Sue Applicazioni, 2012
In this work we studied a system of two partial differential type modeling the motion of some bacteria, which use an Actin-based propulsion mechanism. The resulting system is composed by two equation (a porous-media equation and a linear hyperbolic one)

Abundant Explicit and Exact Solutions for the Variable Coefficient mKdV Equations

open access: yesAbstract and Applied Analysis, 2013
This paper is concerned with the variable coefficients mKdV (VC-mKdV) equation. First, through some transformation we convert VC-mKdV equation into the constant coefficient mKdV equation.

Some non-linear s.p.d.e.'s that are second order in time

open access: yes, 2002
We extend Walsh's theory of martingale measures in order to deal with hyperbolic stochastic partial differential equations that are second order in time, such as the wave equation and the beam equation, and driven by spatially homogeneous Gaussian noise.

Numerical solution to nonlinear Tricomi equation using WENO schemes

open access: yesElectronic Journal of Differential Equations, 2010
Nonlinear Tricomi equation is a hybrid (hyperbolic-elliptic) second order partial differential equation, modelling the sonic boom focusing. In this paper, the Tricomi equation is transformed into a hyperbolic system of first order equations, in ...

Generation of three-dimensional body-fitted grids by solving hyperbolic and parabolic partial differential equations [PDF]

open access: yes
Hyperbolic grid generation procedures are described which have been used in external flow simulations about complex configurations. For many practical applications a single well-ordered (i.e., structured) grid can be used to mesh an entire configuration,

A dynamical process of several variables

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2018
In the space of ϕ-distributions with values belonging to a Banach space, the process described by the problem of partial differential equation has been considered. Conditions under which the process is dynamic have been given.
