Before that, I spent 4 years here at Univ, Oxford for an undergraduate master's degree in maths and computer science; Bartek also oversaw <a href="https://www.cs.ox.ac.uk/files/14521/masters-thesis.pdf">my master's thesis</a>.</p>
<p>My research interest is in the computation theory with atoms (unfortunately not those of physicists/chemists). The idea is to take a model of computation, replace the finite components &mdash; e.g., the states and the alphabet &mdash; by infinite yet highly symmetric ones, and see what still works / what breaks. In particular I worked on weighted register automata and the corresponding representation theory; to learn more, you could read my <a href="https://www.cs.ox.ac.uk/files/14923/THESIS-PROPOSAL.pdf">thesis proposal,</a> my <a href="https://www.cs.ox.ac.uk/files/14922/LIT-REVIEW.pdf">literature review</a>, and others' papers cited within.</p>
<!--  [For the curious — under all bijections from N to N itself, the infinite set N^2 splits into just two orbits: one containing (1, 1) and another containing (2, 0). So even though Lin N^2 is infinite-dimensional, it has an orbit-finite basis N^2; and if we only care about the vector subspaces that contain whole orbits, we do not have a very long list!] --><h2>Activities</h2><ul class="list-comma-separated"><li><a href="/activities/Nom/"><span itemprop="affiliation">Nominal Techniques</span></a></li></ul><h2>Supervisor</h2><div class="row"><div itemscope="itemscope" itemtype="http://schema.org/Person" class="picturebox col-xs-6 col-sm-4 col-md-3  clear-xs clear-sm clear-md clear-lg"><a class="piccy" href="/people/Bartek.Klin/" style="background-image:url('/files/12993//bk-photo%20copy.jpg')"></a><center><a href="/people/Bartek.Klin/"><span class="newcaption"><span itemprop="name">Bartek&nbsp;Klin</span></span></a></center></div></div>
