On State Complexes and Special Cube Complexes
We find that state complexes are non-positively curved metric spaces, aspherical topological spaces, and have fundamental groups that are subgroups of right-angled Artin groups. In addition, we find that the property state is preserved when taking finite products, as is true in the case of special. …

Configuration Complexes and Tangential and Infinitesimal versions of Polylogarithmic Complexes
… and Cathelineau's infinitesimal polylogarithmic complexes as well as a tangential complex to the famous Bloch-Suslin complex (in weight 2) and to Goncharov's ``motivic`` complex (in weight 3), respectively, as proposed by Cathelineau [5]. Our main result is a morphism of complexes between the …

Generalized Koszul complexes
We introduce Koszul type complexes associated to a linear map from any module to a free module, and vice versa to a linear map from a free module to an arbitrary module, generalizing both the classical Koszul complex and the family of Eagon-Northcott complexes. Given a short complex of finite free …

Precovering Dgc-Complexes
In this thesis we prove that with the hypotheses that dg e C is injectively resolving and that the class C is closed under arbitrary direct limits we have that the following are equivalent to dgC being covering: Every complex of C-modules is in dg e C and every exact complex of C-modules is in e C.

Actinide porphyrin complexes
The first bis(porphyrin)actinide complexes have been prepared by reaction of M(NEt$\sb2$)$\sb4$ (where M = Th, U) with H$\sb2$TPP or H$\sb2$OEP. The coordination geometry of (TPP)$\sb2$Th is a distorted square-prism where the thorium center is displaced 1.47 A from each of the porphyrin N$\sb4$ …

Multidimensional Behavioral Complexes
In a preprint by J. Wood, V. Lomadze, and E. Rogers, chains and boundary maps were defined for 2-D discrete behavioral systems. The corresponding homology groups were studied and tied to trajectory properties. Indeed, the homology groups encapsulated the concepts of autonomy, controllability, and …

Amphiphilic Spin Crossover Complexes
… of amphiphilic iron(II) spin crossover complexes. The prime attention was on the self-assembly ability of the synthesized compounds and the influence of the supramolecular arrangement in the solid on the SCO behaviour. The used ligand system is based on Schiff base-like Jäger ligands …

Thiocyanate complexes of osmium
<p>Osmium is a hard grey brittle metal which scratches glass. It has a melting point of 2700[degree]C, and a specific gravity of 22.4, which is greater than any other known substance. The grey color of osmium resembles the grey color of iron and ruthenium. Osmium was discovered in 1803 by Tennant …

Nitrogen-rich oximic complexes
The complexlng behaviour of chloroglyoxine (cgH2), dichloroglyozime (dcgH2), and diaminoglyoxime (dagH2) towards copper and nickel has been studied.

Cyanide-bridged polynuclear complexes
The three mixed valent dinuclear cyanide-bridged complexes LMCNFeCl3, (LM = Cp(dppe)Fe, Cp(dppe)Ru and Cp(PPh3)2Ru) were synthesized and characterized by X-ray single crystal determination, IR, UV-Vis and cyclic voltammograms, respectively. The three mixed valent dinuclear complexes display metal- …

Maximal Surfaces in Complexes
Cubical complexes are defined in a manner analogous to that for simplicial complexes, the chief difference being that cubical complexes are unions of cubes rather than of simplices. A very natural cubical complex to consider is the complex C(k_1,...,k_n) where k_1,...,k_n are nonnegative integers. …

Splines on polytopal complexes
… in some reasonable sense. For simplicial complexes, such a basis consists of splines which are supported on the union of simplices surrounding a single vertex. Such bases are well known in the case of planar triangulations for $d\ge 3r+2$~\cite{HongDong,SuperSpline}. In …
