We show that on every vertical line s= σ+ it with σ∈ (1 / 2 , 1) , these L-functions simultaneously take large values of size exp(c(logt)1-σloglogt) inside a small neighborhood. Our method extends to σ= 1 unconditionally, and to σ= 1 / 2 on the generalized Riemann hypothesis. We also obtain similar joint omega results for arguments of the given L-functions.falseArticle143218231177-1190October 20223arJournal3WOS:000841043300004
