Solutions to the non-autonomous ABS lattice equations: Casoratians and bilinearization

Ying Shi, Da-jun Zhang, Song-lin Zhao

In the paper non-autonomous H1, H2, H3${}_{\delta }$ and Q1${}_{\delta }$ equations in the ABS list are bilinearized. Their solutions are derived in Casoratian form. We also list out some Casoratian s…
