The calculation of next-to-leading log x corrections to the BFKL equation was completed last year [ 1, 2] after several years of theoretical effort. The results, for both anomalous dimension and hard Pomeron, show however signs of instability due to both the size and the (negative) sign of corrections, possibly leading to problems with positivity also [ 3]. If we write the eigenvalue equation c...
