摘要
A method is put forward to establish the lower bounds for some n-color classical Ramsey numbers R(q,q,(...),q) = R-n (g). With this method six new explicit lower bounds R-4(4) greater than or equal to 458, R-3(5) greater than or equal to 242, R-3(6) greater than or equal to 1070, R-3(7) greater than or equal to 1214, R-3(8) greater than or equal to 2834 and R-3(9) greater than or equal to 5282 are obtained using a computer.
