Exact solution and finite size properties of the U q [osp(2|2m)] vertex models Abstract We have diagonalized the transfer matrix of the U q [osp(2|2m)] vertex model by means of the algebraic Bethe ansatz method for a variety of grading possibilities. This allowed us to investigate the thermodynamic limit as well as the finite size properties of the corresponding spin chain in the massless regim...

Informação, aprendizagem e criação do conhecimento em comunidades de prática: um estudo de caso

Information, learning and knowledge creation in communities of practice: a case study. This research aimed to investigate the functioning of communities of practice, considering the following aspects: information processing, learning and creation of tacit knowledge. The investigation was made in Service Desk Microcity, mediumsized company with a high level of computerization, which offers IT ma...

The Bethe ansatz approach for factorizable centrally extended su(2|2) S-matrices Abstract We consider the Bethe ansatz solution of integrable models interacting through factor-ized S-matrices based on the central extention of the su(2|2) symmetry. The respective su(2|2) R-matrix is explicitly related to that of the covering Hubbard model through a spectral parameter dependent transformation. Th...
