I am a Professor of Pure Mathematics in the Department of Mathematical Sciences at the University of Bath. This page is here to give some basic information and to direct visitors, most of whom are me, to more useful pages:

Mathematicians' personal web pages are expected to have a picture of them in an interesting foreign city. This one is in St Petersburg. It was taken at a time when visiting St Petersburg was a reasonable and practical thing to do.

My email address is `gksankaran@gmail.com` and I don't
care who knows it. For Bath University official and internal matters,
use `G.K.Sankaran@bath.ac.uk` instead.

Other ways to contact me, in order of decreasing usefulness:

- My office is
`4W5.16`, at snacks.wedge.stove. The office number does mean something. W means West of the library, which is further from the bus stop: 4 is an even number so it is on the south side, opposite the library. 5 means the fifth floor, but the count goes from the basement so if you are on the Parade you are at level 2, so you need to go up three levels to find my office. Here are some directions, and a map. - Postal address:

Department of Mathematical Sciences,

University of Bath

Bath BA2 7AY

UK - Office phone:
`+44 (0)1225 386220`. There is no phone: this sets off Teams and would cause my computer to ring, except that the sound is off - Skype:
`gksankaran`, but you have to do this by appointment. - The Site Formally Known As Twitter: I am
`@gks1`but I don't use it much. - I am not on any other social media of any kind, especially Facebook.
- Other coordinates (my home address, my mobile number, the landline at home) are available if and only if I have given them to you.

My mathematical interests are mainly in algebraic geometry.

It is impossible to have interests entirely in algebraic geometry, because algebraic geometry is too big. In my case, some of what I do could be described as number theory, and a few bits could be described as topology, algebra, complex analysis or even (this always surprises me) computer science.

My mathematics research page carries a list of my papers. It also tells you about my research students, past and present.

I teach one or two courses a year, depending on how big they are. They are usually algebra, number theory or geometry. Teaching is fun, but unfortunately it is associated with other things, such as exams, which are no fun for anybody. Exams are the worst way of finding out how a student has progressed, except for all those other ways that have been tried from time to time.

My teaching page carries a list of my teaching, with links to some possibly still useful web pages.

I do various other things that are difficult to classify but are related to my job.

In 2018 I was elected to the University of Bath Senate, which is the ultimate academic authority of the university. I lost my seat in the election in 2021, by the narrowest possible margin. I have still not made up my mind whether I was disappointed or relieved, but I have not been a candidate since.

I am a local Bath organiser of the COW seminar but I ceased to be the main organiser in 2018. I am still one of the owners of the mailing list, though, so if you want to join it you can do that by emailing me.

The UK Algebraic Geometry Network was started in 2023 to provide UK-wide network activities in algebraic geometry, building on the experience of COW and GLEN. It is funded by a Network Support for the Mathematical Sciences grant from the Isaac Newton Institute, via EPSRC grant EP/V521929/1,and is coordinated by six people, one of whom is me.

In 2020, Bath hosted LMS Prospects in Mathematics: online in the end, of course. I was one of the organisers.

In 2023, Bath hosted the British Mathematical Colloquium. I was one of the organisers.

I was a co-I on the EPSRC-administered, GCRF-funded project
EP/T001968/1 entitled *Capacity building in Africa via
technology-driven research in algebraic and arithmetic
geometry*. The planned activities involved travel to and from
Africa in 2020 and 2021, so they were wiped out, but this is one part
of the wider Abram Gannibal Project, which aims
to assist the development of high-level mathematics in Africa. The
actual development must, of course, be done by Africans.

In May 2025 we will run a meeting funded by the ICMS
programme Mathematics
for Humanity with the title *Algebra and Geometry from
Africa*.

I am on a few advisory committees:

- London Mathematical Society Council, and a couple of committees and working parties associated with that.
- The EPSRC Peer Review College, which means that if you write a grant proposal in a subject I know something but not too much about, there is a good chance I'll end up reading it.
- The EPSRC Mathematics Strategic Advisory Team, which means EPSRC ask us what we think about their plans and we tell them.
- The Programme Committee of the International Centre for Mathematical Sciences in Edinburgh, which is the committee that decides which proposals for events at ICMS get funded.
- The Conseil Scientifique (CSI) of the Institut national des sciences mathématiques et de leurs interactions (INMSI), part of CNRS (French academic administration is the world's largest civilian producer of acronyms).
- Nesin Mathematical Village hosts a series of Geometry-Topology Schools and I am on the scientific committee of that series.

The Bath University Venturers Cricket Club is a University team open to all staff and graduate students of the University of Bath, and therefore belongs on this professional page. I play for it, and I organise the fixtures.

My personal page is strictly unofficial and explains a bit more about who I am and what I am interested in.
