I have always found [union closed conjecture](https://en.wikipedia.org/wiki/Union-closed_sets_conjecture) very interesting. There is an [arxiv article](https://arxiv.org/abs/1507.01270) claiming the solve the problem. My background is not appropriate to read the proof. Is this proof verified or wrong? Any comment would be appreciated. 


The article was submitted in 2015 and it is not too long(about ten pages). Thus, I expect that it should be verified until now.



Is this proof of union closed set conjecture verified?
There is a recent [thesis](https://repositorio-aberto.up.pt/bitstream/10216/87152/2/158981.pdf) by André da Cruz Carvalho on this conjecture. It discusses the paper by Vladimir Blinovsky and shows why his proof does not work (page 16). NB: I have not read it carefully, and this refers to the first version of Blinovsky's paper.
