 OK, so it's really a pleasure to organize this conference today with Huawei. So probably the first talk will be given by Francis instead of Cédric, because Cédric is at Francaintère speaking about his new book. So he would be 15 minutes late, so maybe we just change the two first talks. OK, so I would like to say a very few things about IHES. So I don't know if it's the first time for you here. So IHES was founded more than 57 years ago, something like this. And we are in Bure-sur-Hivette for since 52 years. And the idea was to build a scientific institute on the model of the Institute for Advanced Study in Princeton. And we had the chance to have very high level professors from the start, including Grotendic, Deline, René Tom. And so around these small numbers of professors, we host a huge program of visitors. So we have more than 200 visitors every year, and coming, say, for an average of two months and a half. And so at any time, there are 50 scientists at the Institute. So IHES is a little bit unique in France because it's a private company. And somehow, we have a status of being in the interest of the public. So half of our budget is coming from the government. And we have to find support for the rest of our budget. And for this reason, we had to discuss with a lot of institutions in Europe, like EPSRC, SwissFond, Max Planck-Gazelschaff, or NSF in the US. But we have also to have contact with companies. And during the last 20 years, several companies helped us a lot, including the group AXA, the Schlumberger, who founded the Cher Schlumberger here and other institutions. And I think that maybe six or seven years ago, IHES started to have contact with Huawei. And we never stopped this contact. And Huawei supported us the first time maybe five years ago. And maybe I'm not sure. And recently, Huawei decided to create a very active research center in Paris, or near Paris. And at this occasion, we had a lot of discussion, including with Merwin and a lot of people from Huawei. And after this discussion, Huawei decided to help us a lot. And we thought that the nicest way to organize our collaboration was to organize conferences, like the one we are running today. So I hope that around this talks, there will be a lot of discussions between people from Huawei and scientists who are just attending the conference. And I really want to wish you very good luck for what you are starting to develop, and it's a very ambitious project. So I think you are starting something which may be important. And so I wish you the best for all of us. So I would like to add that it was very nice for me to organize the conference with Merwin. It was quite easy. And I would like to thank you for this. OK, so first of all, I'm very happy that IHES hosted this event here. And also for the organization of this workshop and getting the best speakers within the Paris region. As you know, France has one of the highest rank of, I would say, highest concentration of mathematicians. And Paris has also the highest concentration of mathematicians around the world. And Huawei acknowledged that. And it's one of the reasons this mathematical and algorithmic sciences lab was established in Paris. So for people who are not aware, Huawei is one of the leading companies in the ICT business. We are in the carrier business, what they call Bay Stations and what we sell for operators. We're also leading the handset business. I think now you're, at least I think you got now, a Huawei phone. I saw it. But in case now you've seen in different, I would say, stores our phones. And I think it's going to be increasing in the next years. And also we are also in the enterprise business, where we sell also our equipments there. Huawei is a company of around 150,000, 60,000 people, which is a big. And half of that is related to R&D, which makes it a very techno-oriented company. Now it turns out, as you know, that the company is evolving. Innovation for many companies is the way to go. And Huawei has been heavily investing in that innovation aspect. It has established this lab for that, because it thinks that French mathematicians are the best in the world, and we think that's where the innovation is going to come from there. Now of course, this is a scientific day. We're going to talk mostly about research aspects and new ideas from great people here. As you know, we give money to, I would say, institutions like Yesh Rez, of course, to create knowledge. And our business is to invert that process and from knowledge make it money. And of course, this is one of the things we are trying to work on. And I hope this collaboration that we started is going to be effective in the next years and going forward. So I hope you're going to enjoy the day. As Emmanuel told you, Cedric Villani is going to be a bit late. I think he's going to come with his motor scooter or something like that directly from Paris. He's got an interview because he's selling his new book. And of course, Francis Bach accepted to be the first speaker, so I'd like to introduce him. And so then he starts his speech.
