Federer has not achieved more than Lao San

At the moment it should be one of the top four, and there is no most in it:

Laver has two Grand Slams, but he is older and has limited competition;

Borg won the French Open three times in a row at Wimbledon and did not have a Grand Slam on any other court;

Sampras has been No. 1 at the end of the Grand Slam for six consecutive years at most, without the French Open;

Federer: The record for the most dominant in a few years is still being set and is not yet available.

The number of Grand Slams is 14 for Sampras, 11 for Laverberg and 11 for Federer (12 at the US Open in two days?). But Sampras can't get to the net so he can't be called better than La Volborg, and neither is Federer. At present, these four people are the most, and there is no public opinion on who is better than whom.

If Federer wins the next French Open, he's the greatest; Or more than 14 Grand Slams outside the French Open (which is a certainty!). And if you are ranked first for more than 6 years at the end of the year, you will surpass Sampras. Of course, I want everyone to be undeniable that there is no controversy, that is, there are more than 14 Grand Slams, including the French Open.

Two representatives of different eras.

In fact, everyone likes to compare them, because they each support their idols, the two represent different eras, but create the same glory, I may belong to Federer's era, so I hope Federer can break Lao San's record.

Feller contributed to the theory of probability and its applications. He has published a series of works on the general form of the law of stacked logarithms, the amplitude theory of recursive events, the limit theorem in empirical distributions, and so on. With regard to the Markov process, Feller extended the Füccer Planck partial code imitation differential equation to some type of integral-differential equation, and used the methods of classical analysis to partially solve the problem.

In the diffusion process, Feller introduced the general differential operator. From the perspective of probability theory, Feller also studied the expansion of the smallest operator that makes it a positive definite half-group of generating operators for the Laplace operator and similar operators in it, and he also generalized this result to multidimensional space and made various explorations. Feller made important achievements in the fields of genetics, physics, and economics, and his book Probability Theory and Its Application Guide (1957) was translated into Chinese and published by Science Press in 1979.

In mathematics, the names that bear his surname are: Feller process, Feller chain, Feller semigroup, etc.

1 All Here are some of the records that belong to Federer:

1 Federer has not been down since he ascended to the world No. 1 position on February 2, 2004, and it will be some time before Sampras continues to record 286 consecutive weeks of world No. 1.

3 Federer's three-in-a-row US Open title, previously achieved by McEnroe and Lendl, Federer won back-to-back Wimbledon-US Open titles for three consecutive years, a record unprecedented.

3 Won three of the four Grand Slams this season: the Australian Open, Wimbledon and the US Open.

5 Federer has lost only five times so far this season, four of them to Nadal and one to British teenager Murray in Cincinnati, although Federer has won 70 matches this season since reaching the US Open final.

6 Federer has reached six Grand Slam finals in a row since Wimbledon 2005, winning five titles and one runner-up (winners: Wimbledon '05, US Open '05, Australian Open '06, Wimbledon '06, US Open '06; Runner-up: French Open '06).

8 He has won eight tournaments this season: Doha, Australian Open, Indian Wells Masters, Miami Masters, Halle Lawn, Wimbledon, Toronto Masters, US Open.

9 14 Federer has won nine of the last 14 Grand Slam tournaments (two Australian Open, four Wimbledon and three US Open) and one runner-up (French Open '06).

461 125 Federer's professional record is 461-125 after the US Open final, and his record so far this season is 70-5 and 81-4 for the whole of 2005.

With 1324 points for the championship season, Federer also plans to play in the Japan Open, Madrid Masters, Switzerland, Paris Masters and Shanghai Masters this season.

The 7,760 World Ranking points set a new record for the highest number of points ever scored in the ATP points system.
