2010/11/24
Our main result states that every fixed-point free continuous self-map of ${\mathbb R}^{n}$ is colorable. This result can be re-formulated as follows: A continuous map $f: {\mathbb R}^{n}\to {\mathbb...

2010/11/23
In his volume [5] on "Symmetry Breaking for Compact Lie Groups" Mike Field quotes a private communication by Jorge Ize claiming that any bifurcation problem with absolutely irreducible group action wo...
Fixed Point Properties of the Ising Ferromagnet on the Hanoi Networks
Fixed Point Properties Ising Ferromagnet Hanoi Networks
font style='font-size:12px;'>
2010/11/18
The Ising model with ferromagnetic couplings on the Hanoi networks is analyzed with an exact
renormalization group. In particular, the fixed-points are determined and the renormalization-
group flow...

We measure the renormalized coupling in the Twisted Polyakov loop scheme for SU(3) gauge
theory coupled with Nf =12 fundamental fermions. To find the infrared fixed point of this theory,we focus on t...

The paper is a survey of some results about Weil algebras applicable in differential geometry, especially in some classification questions on bundles of generalized velocities and contact elements. M...
On Fixed-point theorems in Intuitionistic Fuzzy metric Space
Fixed-point theorems metric Space

2010/11/12
In this paper, first we have established two sets of sufficient conditions for a mapping to have unique fixed point in a intuitionistic fuzzy metric space and then we have redefined the contraction ma...
A General Fixed Point Theorem for Weakly Compatible Mappings in Compact Metric Spaces

In this paper, by using the concept of p-convergency we obtain two fixed point theorems for (q1, q2)-contraction of (, λ)-type and generalized C-contraction.
A Simplicial Approach for Discrete Fixed Point Theorems
Sperner’s lemma Fixed point theorem Direction-preserving map Simplicial structure
font style='font-size:12px;'>
2012/11/30
We present a new discrete fixed point theorem based on a variation of the direction-preserving maps over simplicial structures. We show that the result is more
general than the recent discrete fixed ...
