DIAGONAL RAMSEY NUMBERS "WATERMAN CONJECTURE of 2010" As of September 2010...I changed the lettering assigned in my formulas to better comply with standard lettering....however, all my conjectured Ramsey values remained totally unchanged. "Erdo"s asks us to imagine an alien force, vastly more powerful than us, landing on Earth and demanding the value of R(5, 5) or they will destroy our planet. In that case, he claims, we should marshal all our computers and all our mathematicians and attempt to find the value. But suppose, instead, that they ask for R(6, 6). In that case, he believes, we should attempt to destroy the aliens."
Perhaps we could just use my formula below, instead ?

The classic Ramsey problem can be phrased in terms of guests at a party. What is the minimum number of guests at a party that need to be invited so that either at least three guests will all know each other or be mutual strangers? Answer 6. Suppose we want not a threesome but a foursome who either know each other or are mutual strangers? Erdos and Ramsey theorists have proved that 18 guests are required. For a fivesome, that answer is believed to be 43 to 49. For a sixsome...102 to 165. I propose the following values (for numbers up to a trillion) are for additional levels, without any proof..."the Waterman diagonal Ramsey conjecture". Values have been obtained through the use of my following formula R = s(s-1) 2 k-s where R = Ramsey number |

The classic Ramsey problem only relates 3 guests as a basic unit. The stipulation is that any 3 guests which arrive together must be either strangers or be acquainted. However, what if this unit group of 3 guests were extended to a unit group of 4 guests. That is, invited guests arrive in blocks of 4, all of which must be either mutually acquainted or all strangers to one another. Later, they can mingle indisciminately. The charts below indicate these increased unit groups for all additional Ramsey values up to a trillion. I also have conject regarding a more generalized formula for these "supplimentary" Ramsey numbers... conjectured... |
