Hi everyone! I’m Tyler, a geometer who studies higher-dimensional spaces using dualities from string theory. I also organised the #lgbtsteminar20 yesterday! I’m also a big Eurovision geek. #LGBTQScience

The 1980s murder of a gay maths PhD student in Sydney finally solved. Many gay men were attacked at this time. I was mugged once and narrowly escaped a homophobic attack with the help of the whistle we used to carry around at all times back then.

The story is both tragic and grimly familiar.
It appears that a man, unable to accept his own homosexuality, murdered Scott Johnson, the representative of his desire.
Scott, like others before and since, died because society teaches children homophobia. smh.com.au/national/nsw/s

I am just wanting to point out the comment section without adding anything but a content warning.
CW: hate against the LGBTQ+ community.

Mathematicians in the comments proving exactly why we need this. Y’all can say you don’t care about a mathematician being LGBTQ+ but your comments show once again that deep down you do care. Do better or go eff yourself. Disrespectfully.

We spent a fair amount of time trying to make it readable to those new to tropical geometry (like myself!) and to those new to r-spin theory. I hope people from various communities may like it. (7/n)

Such uniqueness is realistic when you have a strong recursive formula like in this case. We make a novel but equivalent version to the standard WDVV relations and then clock the right piecewise polynomial that satisfies the right properties that make the function unique. (6/n)

Essentially, a neat way to prove a formula like this is to have a reconstruction result saying that if a function whose domain is the set which will have invariants satisfies certain properties then it is unique. (5/n)

We give an explicit formula for them.
We do this by using the cohFT structure, but we show that doing so is equivalent to doing so by using tropical intersection theory, which is how we landed on our new flavour of recursion between invariants. (4/n)

They are natural in mirror symmetry, being an enumerative theory for a Landau-Ginzburg model. They also enjoy rich properties such as having a cohomological field theory (cohFT). (3/n)

In this paper, we look at r-spin invariants. Roughly speaking these are characteristic classes on the moduli space of curves with r-spin structures that can be found by taking the Euler class of a Witten bundle over a connected component of the moduli space. (2/n)

I am looking for a postdoc who is excited about developing mathematical and machine-learning models to study age-related diseases, with a specific focus on the effect of mechanical signatures on disease progression. Please RT

I'm at BBC HQ in London where there is a statue of George Orwell and his words
"If Liberty means anything at all, it means the right to tell people what they do not want to hear."

Ok why did you link my publication profile to this train wreck of a personal account on Twitter. I don’t know how I feel about that.

Today I went to the #BriannaGhey vigil in Birmingham. It was very powerful and articulated the urgency of safety of trans people and trans rights. Now. #TransRightsAreHumanRights

This week, I spoke at the 15th ALGA at IMPA. My time at IMPA has been great and everything was so well organised, even down to their recording of my talk, which I will leave here if you are interested. Lots more interesting talks on their channel too!

Non-LGBTQ people don’t get to say who are allies, what activities make people good allies, or what allyship should look like.

If you think the NSF should be making LGBT people more visible and actually counted, sign this. docs.google.com/document/u/0/d

A legend is now not with us. I met him on zoom in a MPIM seminar this year, but I had read him far before then. What a visionary and role model for how to act curious and kind in our field.

Our student village Selly Oak is 1/9 non straight. Other universities have similar percentages. Our faculties are nowhere near that.

We need to be asking how we support these students. They certainly don’t see open representation in the faculty that matches their student population.

The ONS just published where not straight people lived in the UK yesterday. Essentially it’s cities and, in particular, universities in cities.
