Zilber's Quasiminimality Conjecture states that the complex field equipped with the exponential function is quasiminimal, i.e. every definable subset is countable or co-countable. Despite remaining open, this conjecture led to multiple new concepts and results. One of the directions inspired by the conjecture is the investigation of analogous conjectures where the exponential map is replaced with another function or a function-like object. In most cases the obtained conjecture seems to stay as difficult as the exponential one; as pointed out by Koiran and Wilkie, it even remains open whether adding all entire functions to the complex field would make it quasiminimal or non-quasiminimal. In this talk we provide two quasiminimal examples of this sort: first one involves a correspondence between two elliptic curves, while the second one considers the theory of a generic function, as introduced by Zilber in 2002.

Telegram has gained a reputation as the “secure” communications app in the post-Soviet states, but whenever you make choices about your digital security, it’s important to start by asking yourself, “What exactly am I securing? And who am I securing it from?” These questions should inform your decisions about whether you are using the right tool or platform for your digital security needs. Telegram is certainly not the most secure messaging app on the market right now. Its security model requires users to place a great deal of trust in Telegram’s ability to protect user data. For some users, this may be good enough for now. For others, it may be wiser to move to a different platform for certain kinds of high-risk communications. "The argument from Telegram is, 'You should trust us because we tell you that we're trustworthy,'" Maréchal said. "It's really in the eye of the beholder whether that's something you want to buy into." The news also helped traders look past another report showing decades-high inflation and shake off some of the volatility from recent sessions. The Bureau of Labor Statistics' February Consumer Price Index (CPI) this week showed another surge in prices even before Russia escalated its attacks in Ukraine. The headline CPI — soaring 7.9% over last year — underscored the sticky inflationary pressures reverberating across the U.S. economy, with everything from groceries to rents and airline fares getting more expensive for everyday consumers. Either way, Durov says that he withdrew his resignation but that he was ousted from his company anyway. Subsequently, control of the company was reportedly handed to oligarchs Alisher Usmanov and Igor Sechin, both allegedly close associates of Russian leader Vladimir Putin. Crude oil prices edged higher after tumbling on Thursday, when U.S. West Texas intermediate slid back below $110 per barrel after topping as much as $130 a barrel in recent sessions. Still, gas prices at the pump rose to fresh highs.
