A SOUND TYPE SYSTEM FOR SECURE FLOW ANALYSIS
, 1996
"... Ensuring secure information ow within programs in the context of multiple sensitivity levels has been widely studied. Especially noteworthy is Denning's work in secure ow analysis and the lattice model [6][7]. Until now, however, the soundness of Denning's analysis has not been established ..."

Virtual time and global states of distributed systems.
 Proc. Workshop on Parallel and Distributed Algorithms,
, 1989
"... Abstract A distributed system can be characterized by the fact that the global state is distributed and that a common time base does not exist. However, the notion of time is an important concept in every day life of our decentralized \ r eal world" and helps to solve problems like getting a c ..."

consistent population census or determining the potential causality between events. We argue that a linearly ordered structure of time is not (always) adequate for distributed systems and propose a generalized nonstandard m o del of time which consists of vectors of clocks. These clockvectors are p
The modular hierarchy of the Toda lattice
 Diff. Geom Appl
"... The modular vector field plays an important role in the theory of Poisson manifolds and is intimately connected with the Poisson cohomology of the space. In this paper we investigate its significance in the theory of integrable systems. We illustrate in detail the case of the Toda lattice both in Fl ..."

The Toda lattice is superintegrable
 Physica A
, 2006
"... We prove that the classical, non{periodic Toda lattice is super{integrable. In other words, we show that it possesses 2N 1 independent constants of motion, where N is the number of degrees of freedom. The main ingredient of the proof is the use of some special action{angle coordinates introduced by ..."

Bicomplexes and finite Toda lattices
, 1999
"... We associate bicomplexes with the finite Toda lattice and with a finite Toda field theory in such a way that conserved currents and charges are obtained by a simple iterative construction. In recent work [1, 2] we have demonstrated how bicomplexes can be associated with several completely integrable ..."

Toda lattice GStrands
"... Hamilton’s principle is used to extend for the Toda lattice ODEs to systems of PDEs called the Toda lattice strand equations (TStrands). The TStrands in the nparticle Toda case comprise 4n − 2 quadratically nonlinear PDEs in one space and one time variable. TStrands form a symmetric hyperbolic L ..."

Toda Lattice Models with Boundary
, 1995
"... We consider the soliton solutions in 1 and (1+1)dimensional Toda lattice models with a boundary. We make use of the solutions already known on a full line by means of the Hirota’s method. We explicitly construct the solutions satisfying the boundary conditions. The Z∞symmetric boundary condition ..."

Submodular functions, matroids and certain polyhedra
, 2003
"... The viewpoint of the subject of matroids, and related areas of lattice theory, has always been, in one way or another, abstraction of algebraic dependence or, equivalently, abstraction of the incidence relations in geometric representations of algebra. Often one of the main derived facts is that all ..."
