Spectroscopic Variations of the Be-shell Star EW Lac in the V/R Variation Periods
Masahiro Mon, Masakazu Suzuki, Yuki Moritani +1
EW Lac has shown remarkable V/R variations in 1976 - 1986, and a similar V/R variation has started again in around 2007, after some quasi-periodic V/R variation. For the first V/R…
All Link Invariants for Two Dimensional Solutions of Yang-Baxter Equation and Dressings
N. Aizawa, M. Harada, M. Kawaguchi +1
All polynomial invariants of links for two dimensional solutions of Yang-Baxter equation is constructed by employing Turaev's method. As a consequence, it is proved that the best i…
Noncommutative Geometry of Super-Jordanian Covariant Quantum Space
N. Aizawa, R. Chakrabarti
Extending a recently proposed procedure of construction of various elements of diffential geometry on noncommutative algebras, we obtain these structures on noncommutative superalg…
Weak Hopf algebras corresponding to
N. Aizawa, P. S. Isaac
We investigate the weak Hopf algebras of Li based on and Sweedler's finite dimensional example. We give weak Hopf algebra isomorphisms between the weak generalisations…
