I am due to give a talk at a conference to celebrate the retirement of Professor Roger Grimshaw, it’s quite a big international conference with some very big names giving talks and therefore it should be very worthwhile attending. I will be giving a talk on my latest work which is a generalisation of my previous work from two dimensions to three. I believe I have given the first physical derivation of the 5th order KP equation with an external electric field with a moving pressure distribution. I think that it can also be used to extent the Benjamin-Ono equation as well as it includes a Hilbert transform term. My talk.
