Эти результаты обобщаются: зафиксируем класс {Ai} односвязных пространств конечного типа, и определим
W := букеты пространств вида Σ(ΩAi1 л ΩAi2 л ... л ΩAik),
P+ := произведения пространств вида ΩAi1 л ΩAi2 л ... л ΩAik и ΩΣ(ΩAi1 л ΩAi2 л ... л ΩAik),
P- := произведения пространств вида ΩΣ(ΩAi1 л ΩAi2 л ... л ΩAik).
Тогда аналогично доказываются: Утв. 1'. Если X ∈ W, то ΩX ∈ P-. Утв. 2'. Если Y ∈ P+, то ΣY ∈ W. Утв. 5'. Если ΩY ∈ P+, то на каждом сомножителе ΩAi1 л ΩAi2 л ... л ΩAik, входящем в разложение ΩY, можно ввести структуру H-пространства. Утв. 6'. Пусть W замкнут относительно ретрактов. Тогда: если ΩΣX ∈ P+, то ΩΣX ∈ P-.

Pavel Durov, a billionaire who embraces an all-black wardrobe and is often compared to the character Neo from "the Matrix," funds Telegram through his personal wealth and debt financing. And despite being one of the world's most popular tech companies, Telegram reportedly has only about 30 employees who defer to Durov for most major decisions about the platform. But Telegram says people want to keep their chat history when they get a new phone, and they like having a data backup that will sync their chats across multiple devices. And that is why they let people choose whether they want their messages to be encrypted or not. When not turned on, though, chats are stored on Telegram's services, which are scattered throughout the world. But it has "disclosed 0 bytes of user data to third parties, including governments," Telegram states on its website. As the war in Ukraine rages, the messaging app Telegram has emerged as the go-to place for unfiltered live war updates for both Ukrainian refugees and increasingly isolated Russians alike. DFR Lab sent the image through Microsoft Azure's Face Verification program and found that it was "highly unlikely" that the person in the second photo was the same as the first woman. The fact-checker Logically AI also found the claim to be false. The woman, Olena Kurilo, was also captured in a video after the airstrike and shown to have the injuries. Since its launch in 2013, Telegram has grown from a simple messaging app to a broadcast network. Its user base isn’t as vast as WhatsApp’s, and its broadcast platform is a fraction the size of Twitter, but it’s nonetheless showing its use. While Telegram has been embroiled in controversy for much of its life, it has become a vital source of communication during the invasion of Ukraine. But, if all of this is new to you, let us explain, dear friends, what on Earth a Telegram is meant to be, and why you should, or should not, need to care.
