摘要：

Consider the one-dimensional SDE X-t = x+ Sigma(i=1)(infinity) integral(0)(1)sigma(i)(X-s) dW(s)(i) + integral(0)(1)b(X-s) ds, where W-i is an infinite sequence of independent standard Brownian motions, i = 1, 2, 3,... . We prove two theorems on the existence and uniqueness of solutions with non-Lipschitz coefficients, and give a non-contact property and a strong comparison theorem for solutions.
