<p>Dear all,</p>
<p>Tomorrow, on <b>Friday</b> <b>May 30th at 2pm</b> we will hear
from <b>Melika Norouzbeygi</b> in the <b>peripatetic seminar</b>.<br>
</p>
<p><i>Title</i>: Actegories and Copowers with Application to Message
Passing Semantics<br>
<br>
<i>Abstract</i>: In this talk we prove that giving a right
actegory with hom-objects is equivalent to giving a right-enriched
category with copowers. While this result is known in the closed
symmetric setting, our contribution extends the equivalence to
non-closed and non-symmetric monoidal bases. This generalization
is motivated by the semantics of higher-order message passing in
the <b>Categorical Message Passing Language (CaMPL)</b>, a
concurrent language whose semantics is given by a linear actegory.
A desirable feature for this language is the support of
higher-order processes: processes that are passed as first class
citizens between processes. While this ability is already present
in any closed linear type systems -- such as <b>CaMPL</b>'s -- to
support arbitrary recursive process definitions requires the
ability to reuse passed processes. Concurrent resources in <b>CaMPL</b>,
however, cannot be duplicated, thus, passing processes as linear
closures does not provide the required flexibility. This means
processes must be passed as sequential data and the concurrent
side must be <b>enriched</b> in the sequential side, motivating
the technical result of this paper.</p>
<p>It will take place on Friday May 30th at 2pm in ICT 616.</p>
<p>Looking forward to seeing you there!<br>
</p>
<p>Best regards,</p>
<p>Florian<br>
