# North British Mathematical Physics Seminar 47

The forty-seventh meeting of the North British Mathematical Physics Seminar will take place on

**Thursday 23rd June 2016**
at the **King's Manor, University of York**.

Note: these people participated.

The
King's Manor is in the centre of the city,
5 minutes' walk from the railway station. To get there, turn left out of the station, under the wall, left over the bridge over the river,
then left after 100m at the crossroads (see map). The King's Manor is in Exhibition Square, to the
left of the fountain and the city art gallery.

Refreshments will be in the refectory and lunch in cafes nearby. To get to the refectory go through the porters' lodge and up the stone
staircase towards the end of the first court on the left. Talks will be in **K/133**, entered either through the refectory (back of the theatre) or at the far left-hand corner of the furthest court (which brings you in at the front of the theatre).

## Programme

1100-1200

Balt van Rees
(Durham)

TBA

1400-1500

Vidas Regelskis
(York)

In this talk I will discuss the problem of classifying solutions of the trigonometric reflection equation in the context of Drinfeld-Jimbo quantum groups. I will explain a class of coideal quantum groups given by quantum symmetric Kac-Moody pairs introduced by Kolb and Letzter that will be used to obtain the aforementioned classification for vector representation of quantum loop algebras of classical (A, B, C, D) Lie type. I will then discuss two types of equivalence of reflection matrices, rotation and dressing, both of which are induced by the notion of equivalence of coideal subalgebras (in terms of Hopf algebra automorphisms). Many concepts will be illustrated in terms of Satake diagrams, which are known to classify the relevant coideal subalgebras. This is a joint work with B. Vlaar.

1545-1615

Veronika Breunholder
(Edinburgh)

In this talk I will present the construction of a new supersymmetric, asymptotically flat black hole solution in the context of five-dimensional minimal supergravity. The solution has an event horizon which is of lens space topology L(3,1). It carries an electric charge, two angular momenta, as well as magnetic dipole charges related to regions of non-trivial topology outside the horizon.

1615-1715

## Practical Information

These maps
will get you from the railway station to King's Manor (the
university-provided one
doesn't show the station).

If you come by car I'm afraid you'll need to take your chances in the city centre car parks.

Limited funds are available to help with travel expenses of those
with no other source of funding, especially postgraduate students and
postdocs. Please book early to take advantage of the cheaper
advance-purchase train fares. For how to claim please see
the main NBMPS page.

If you plan to attend the meeting, or for further questions, please email the
local organisers:

Niall MacKay or
Eli Hawkins.
