Recommended nomenclature for the sapphirine and surinamite groups (sapphirine supergroup)
nomenclature aenigmatite sapphirine surinamite chain silicates.
2013/12/6
Minerals isostructural with sapphirine-1A, sapphirine-2M, and surinamite are closely related chain silicates that pose nomenclature problems because of the large number of sites and potential constitu...
Nomenclature of the apatite supergroup minerals
nomenclature apatite supergroup apatite group hedyphane group belovite group britholite group ellestadite group
2013/12/6
The apatite supergroup includes minerals with a generic chemical formula IXM12 VIIM23(IVTO4)3X (Z 2); chemically they can be phosphates, arsenates, vanadates, silicates, and sulphates. Themaximum sp...
THE PYROCHLORE SUPERGROUP OF MINERALS: NOMENCLATURE
pyrochlore supergroup nomenclature pyrochlore group microlite group betafite group rom閕te group elsmoreite group
2013/12/6
A new scheme of nomenclature for the pyrochlore supergroup, approved by the CNMNC朓MA, is based on the ions at the A, B and Y sites. What has been referred to until now as the pyrochlore group should b...
Nomenclature of the tourmaline-supergroup minerals
Tourmaline mineral chemistry nomenclature substitutions order-disorder
2013/12/6
A nomenclature for tourmaline-supergroup minerals is based on chemical systematics using the generalized tourmaline structural formula: XY3Z6(T6O18)(BO3)3V3W, where the most common ions(or vacancy) at...
Nomenclature of the hydrotalcite supergroup;natural layered double hydroxides
LDH layered double hydroxide hydrotalcite hydrotalcite supergroup brucite nomenclature manasseite sjo¨grenite barbertonite cyanophyllite fouge`rite treⅴbeurdenite.
2013/12/6
Layered double hydroxide (LDH) compounds are characterized by structures in which layers with a brucite-like structure carry a net positive charge, usually due to the partial substitution of trivalent...
Alunite supergroup: recommended nomenclature
nomenclature alunite natroalunite kintoreite beaverite orpheite minamiite
2013/12/6
Minamiite has been discredited and renamed natroalunite-2c to show a double unit-cell structure and natroalunite can be designated as natroalunite-1c to show a single unit-cell structure. Kintoreite c...

Amphibole nomenclature classification chemical composition crystal chemistry
2013/12/6
A new classification and nomenclature scheme for the amphibole-supergroup minerals is described, based on the general formula AB2C5T8O22W2, where A = o, Na, K, Ca, Pb, Li; B = Na, Ca, Mn2+, Fe2+, Mg, ...

2013/12/6
After careful consideration of the semantics of status categories for mineral species names, minor corrections and disambiguations are presented for a recent report on the nomenclature of the pyrochlo...

The Brauer-Picard group of the representation category of finite supergroup algebras
Brauer-Picard group tensor category module category Quantum Algebra
2012/2/29
We develop further the techniques presented in [M. Mombelli. On the tensor product of bimodule categories over Hopf algebras. Preprint arXiv:1111.1610 ] to study bimodule categories over the represent...
Non-chiral current algebras for deformed supergroup WZW models
Non-chiral current algebras deformed supergroup WZW models
2010/12/24
We study deformed WZW models on supergroups with vanishing Killing form. The deformation is generated by the isotropic current-current perturbation which is exactly marginal under these assumptions. I...
Modular branching rules for projective representations of symmetric groups and lowering operators for the supergroup Q(n)
projective representations symmetric groups lowering operators the supergroup Q(n)
2010/11/9
There are two approaches to projective representation theory of symmetric and alternating groups, which are powerful enough to work for modular representations. One is based on Sergeev duality, which...
