Some of my writings can be found online. Below is the list (later I will post here links to some errata and complimentary notes to some of the items). If other authors are not mentioned, the articles are authored just by me (Zoran Škoda). My thesis title was Coset spaces for quantum groups, and the abstract is at the link. For MR numbers see my MR numbers.

Quantum heaps
I introduced quantum heaps in Spring 2001, and they entered as a side-topic (Chapter 9 only) in my thesis. They were rediscovered by Grunspan in 2002 what spurred lots of activity and publications, but unfortunately nobody did refer nor use my work till the publication of my 2007 remake above.

See also related entry symmetric ordering for Lie algebras. We have also exhibited a Hopf algebroid structure on the noncommutative phase space with base coordinate space being a universal enveloping algebra in
A geometric version of this Hopf algebroid, in terms of differential operators on a Lie group is being developed in an article in preparation with my student Martina Stojić. I also work on independent construction of the algebraic version of the Hopf algebroid by a construction of extension of scalars for Hopf algebroids generalized to doubles of certain class of filtered infinite-dimensional Hopf algebras.

Other scientific topics
With my student M. Bašić, I work on a programme of finding the integration objects for Leibniz algebras, which could be called Leibniz groups. Here is a manifesto:
Not included in this manifesto is a discussion of the internal Weyl algebra in the Loday-Pirashvili category which is in the rector prize work of Bašić under my guidance. Also there is my manuscript on certain bialgebras in LP category (roughly speaking).
G. Sharygin and I started to write about unfinished research with tentative title
The PBW isomorphism is not a coalgebra map in the case of algebroids, that is why the correction. We studied this subject at MPIM Bonn in Spring 2010, then a week at IHES in late November 2010 and talked much via skype in April and should continue these days.
In future, I would like to work closer to the BV-quantization program which is now being better geometrically understood.
