The Pashtun Tribal System

We have inherited a somewhat fuzzy usage of the term ‘tribe’ and ‘tribal’ from early British anthropology. ‘Tribe’ was often used in a rather derogatory manner for relatively small ethnic groups who lived as ‘underdeveloped’ (formerly called ‘primitive’ or even ‘savage’) minorities, far from the majorities’ cultural and social mainstream. No wonder that the term ‘tribe’ became obsolete in many ...

Some combinatorial aspects of finite Hamiltonian groups

In this paper we provide explicit formulas for the number of elements/subgroups/cyclic subgroups of a given order and for the total number of subgroups/cyclic subgroups in a finite Hamiltonian group. The coverings with three proper subgroups and the principal series of such a group are also counted. Finally, we give a complete description of the lattice of characteristic subgroups of a finite H...

Some aspects of cosheaves on diffeological spaces

We define a notion of cosheaves on diffeological spaces by cosheaves on the site of plots. This provides a framework to describe diffeological objects such as internal tangent bundles, the Poincar'{e} groupoids, and furthermore, homology theories such as cubic homology in diffeology by the language of cosheaves. We show that every cosheaf on a diffeological space induces a cosheaf in terms of t...

Some Aspects of Transversity∗

The specificities of transverse polarization with respect to helicity of ultrarelativistic fermions are pointed out. For massless fermions, a covariant transversity four-vector is defined, up to a kind of gauge transformation. The tranversity distribution of quarks in a nucleon is defined. Its possible connection to the magnetic or electric dipole moment of the baryon is conjectured. Consequenc...
