## What are the Hilbert problems?

Hilbert’s problems are 23 problems in mathematics published by German mathematician David Hilbert in 1900. They were all unsolved at the time, and several proved to be very influential for 20th-century mathematics.

## Where did David Hilbert get his education from?

**Why did Grigori Perelman decline the prize money?**

According to Interfax, Perelman refused to accept the Millennium prize in July 2010. He considered the decision of the Clay Institute unfair for not sharing the prize with Richard S. Hamilton, and stated that “the main reason is my disagreement with the organized mathematical community.

### Is the Riemann Hypothesis solved?

The Riemann hypothesis, a formula related to the distribution of prime numbers, has remained unsolved for more than a century.

### What are Hilbert’s problems?

Hilbert’s problems are twenty-three problems in mathematics published by German mathematician David Hilbert in 1900. They were all unsolved at the time, and several proved to be very influential for 20th-century mathematics.

**Is there a 21st century analogue of Hilbert’s problems?**

At least in the mainstream media, the de facto 21st century analogue of Hilbert’s problems is the list of seven Millennium Prize Problems chosen during 2000 by the Clay Mathematics Institute.

#### Are any of David Hilbert’s problems still open to study?

Some of Hilbert’s problems remain open–indeed, the most famous of Hilbert’s problems, the Riemann hypothesis, is one of the seven Millennium Prize Problems as well.

#### How many Millennium Prize Problems have been solved?

To date, the only Millennium Prize problem to have been solved is the Poincaré conjecture. The Clay Institute awarded their monetary prize to Russian mathematician Grigori Perelman in 2010.
