Global existence for a parabolic chemotaxis model with prevention of overcrowding
Hillen T., Painter K. Advances in Applied Mathematics 26(4): 280-301, 2001. Type: Article
In this paper we study a version of the Keller-Segel model where the chemotactic cross-diffusion depends on both the external signal and the local population density. A parabolic quasi-linear strongly coupled system follow...

Algorithm 799: revolve: an implementation of checkpointing for the reverse or adjoint mode of computational differentiation
Griewank A., Walther A. ACM Transactions on Mathematical Software 26(1): 19-45, 2000. Type: Article
This is an excellent paper, describing a variant (“revolve”) of the basic form for reverse differentiation for computing the gradient of a scalar valued function, which enables computing this gradient of a function ...

A constructive implementation of the Cartan-Kähler theory of exterior differential systems
Hartley D., Tucker R. Journal of Symbolic Computation 12(6): 655-667, 1991. Type: Article
A novel approach to the symbolic solution of partial differential equations is offered. The paper describes a procedure for constructing a regular chain of involutive integral elements for a general exterior differential system. This c...
