I'm Spanish so muy mother tongue is Spanish. I write and speak English quite well. I have to do a kind of project at the university about Lax-Milgram theorem and for that I have to write an abstract in English. I read math in English and I understand quite well but I'm not sure about me writing maths in English. Can I post my abstract for a little review? As many of this site can speak or know writing math in English, I want a little help of advice to improve my text, It's very easy, it's not about the mathematical content it would be about the language content. Can I post that in stackexchange or this site it is not about that? Thank you very much.
