IS LOGICALLY NON-TRIVIAL

by Olga Kosheleva, Vladik Kreinovich
"... Abstract. If we express the statement of the unit-distance preserving theorem (that every mapping from R n to R n that preserves unit distance is linear) in terms of quantifiers and logical connectives, then we get a formula that is very close to formulas from elementary geometry. A. Tarski has prov ..."

Periodic Instantons with Non-trivial Holonomy

by Thomas C. Kraan, Pierre Van Baal , 1998
"... We present the detailed derivation of the charge one periodic instantons- or calorons- with non-trivial holonomy for SU(2). We use a suitable combination of the Nahm transformation and ADHM techniques. Our results rely on our ability to compute explicitly the relevant Green’s function in terms of ..."

Loopy belief propagation for approximate inference: An empirical study. In:

by Kevin P Murphy , Yair Weiss , Michael I Jordan - Proceedings of Uncertainty in AI, , 1999
"... Abstract Recently, researchers have demonstrated that "loopy belief propagation" -the use of Pearl's polytree algorithm in a Bayesian network with loops -can perform well in the context of error-correcting codes. The most dramatic instance of this is the near Shannon-limit performanc ..."

USACH/99/06 FERMIONS ON NON-TRIVIAL TOPOLOGIES

by J. Gamboa , 1999
"... An exact expression for the Green function of a purely fermionic system moving on the manifold ℜ × Σ D−1 where Σ D−1 is a (D − 1)-torus is found. This expression involves the bosonic analog of χn = einθ corresponding to the irreducible representation for the n-th class of homotopy but in the fermion ..."

A New Proof that Alternating Links are Non-Trivial

by Iain Moffatt , 2008
"... We use a simple geometric argument and small cancellation properties of link groups to prove that alternating links are non-trivial. Unlike most other proofs of this result, this proof uses only classic results in topology and combinatorial group theory. 1 Statement of Results A link is said to be t ..."

Non-Trivial Realizations of Virtual Link Diagrams

by H. A. Dye , 2005
"... A realization of a virtual link diagram is obtained by choosing over/under markings for each virtual crossing. Any realization can also be obtained from some representation of the virtual link. (A representation of a virtual link is a link diagram on an oriented 2-dimensional surface.) We prove that ..."

Non-trivial Inter-layer Degree Correlations in Heterogeneously Growing Multiplex Networks

by Babak Fotouhi, Naghmeh Momeni
"... Abstract. The multiplex network growth literature has been confined to homogeneous growth hitherto, where the number of links that each new incoming node establishes is the same across layers. This paper focuses on heterogeneous growth. We first analyze the case of two pref-erentially growing layers ..."
