Линейная алгебра: четыре разных подхода к одной задаче
В этой статье разберем четыре задачи из студенческих олимпиад по математике. Условие везде такое: возвести матрицу в какую-то большую степень. Но вместе с этим мы увидим, что в зависимости от того под каким углом посмотреть на задачу актуальными оказываются самые разные разделы линейной алгебры. Поехали!

Groups are also not fully encrypted, end-to-end. This includes private groups. Private groups cannot be seen by other Telegram users, but Telegram itself can see the groups and all of the communications that you have in them. All of the same risks and warnings about channels can be applied to groups. On Telegram’s website, it says that Pavel Durov “supports Telegram financially and ideologically while Nikolai (Duvov)’s input is technological.” Currently, the Telegram team is based in Dubai, having moved around from Berlin, London and Singapore after departing Russia. Meanwhile, the company which owns Telegram is registered in the British Virgin Islands. The Russian invasion of Ukraine has been a driving force in markets for the past few weeks. At this point, however, Durov had already been working on Telegram with his brother, and further planned a mobile-first social network with an explicit focus on anti-censorship. Later in April, he told TechCrunch that he had left Russia and had “no plans to go back,” saying that the nation was currently “incompatible with internet business at the moment.” He added later that he was looking for a country that matched his libertarian ideals to base his next startup. But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat.
