<br> Sazetak:<br>Bicrossproduct construction is one of the ways to obtain the Hopf<br>algebra from two given ones. It was firstly introduced in the case of<br>the kappa-Poincare Hopf algebra.<br>However if one doesn't want to consider the whole Hopf algebra and<br>
resigns from antipodes the same construction can be used for obtaining<br>bialgebra from two given ones. Interestingly, this construction also<br>works if one loses the notion of counit as well. Then we deal with a<br>unital non-counital bialgebra as a result of this construction. The<br>
motivation for introducing that last case is to obtain (weak) coalgebra<br>structure on the Weyl-Heisenberg algebra, which is not possible to be<br>formulated as full bialgebra.<br>In my seminar I will recall some of the definitions necessary for<br>
bicrossproduct contruction and also I will illustrate all the above<br>mentioned cases on examples.<br><br><br><br>Voditelj seminara:<br><font color="#888888"><font color="#888888"><font color="#888888">Goran Duplancic (<a href="mailto:gorand@thphys.irb.hr" target="_blank">gorand@thphys.irb.hr</a>)<br>
