The existence of thick triangulations -- an "elementary" proof
We provide an alternative, simpler proof of the existence of thick
triangulations for noncompact manifolds. Moreover, this proof
is simpler than the original one given in \cite{pe}, since it mainly uses tools
of elementary differential topology. The role played by curvatures in this
construction is also emphasized.Comment: 7 pages Short not
Further results on snakes in powers of complete graphs
AbstractBy a snake in a finite graph G is meant a cycle without chords. Denoted by S(G) the length of a longest snake in G. In this paper we obtain a new lower bound for S(G) in the case where G is the product of d copies of the complete graph on n vertices
On the snake in the box problem
AbstractA snake in a graph is a simple cycle without chords. Denote by s(d) the length of a longest snake in the d-dimensional unit cube. We give a new proof of the theorem of Evdokimov that s(d) > λ2d, where λ is a positive constant
Non-Monochromatic and Conflict-Free Coloring on Tree Spaces and Planar Network Spaces
It is well known that any set of n intervals in admits a
non-monochromatic coloring with two colors and a conflict-free coloring with
three colors. We investigate generalizations of this result to colorings of
objects in more complex 1-dimensional spaces, namely so-called tree spaces and
planar network spaces
The non-equilibrium work relation. Thermodynamic analysis and microscopic foundations
We discuss the conditions for which the non-equilibrium work relation is
valid by means of thermodynamic and microscopic arguments.Comment: 16 pages 1 figur
