Bath Numerical Analysis Seminar, 1st Semester 2017/2018

The Numerical Analysis seminar at Bath has been running continuously since 1986 and features a range of invited talks from distinguished visitors as well as internal talks by staff and students of Mathematical Sciences and other Departments at the University of Bath.

The Bath Numerical Analysis Seminar takes place Fridays at 12.15 in 4W1.7 (also known as the Wolfson Lecture Theatre). Campus maps can be found here.

Everyone is welcome at these talks and don't forget to join us for lunch after the seminar.

Tips for new students on giving talks

Since the audience of the NA seminar contains both PhD students and staff with quite wide interests and backgrounds, the following are some guidelines/hints to make sure people don't give you evil looks at lunch afterwards.

Before too much time passes in your talk, ideally the audience should know the answers to the following 4 questions:
  • What is the problem you're considering?
  • Why do you find this interesting?
  • What has been done before on this problem/what's the background?
  • What is your approach/what are you going to talk about?
There are lots of different ways to communicate this information. One way, if you're doing a slide show, could be for the first 4 slides to cover these 4 questions; although in this case you may want to revisit these points later on in the talk (e.g. to give more detail).

  • "vertebrate style" (structure hidden inside - like the skeleton of a vertebrate) = good for detective stories, bad for maths talks.
  • "crustacean style" (structure visible from outside - like the skeleton of a crustacean) = bad for detective stories, good for maths talks.

If you have any queries, please email Silvia (
