A Class of Exponential Sequences with Shift-Invariant Discriminators
Sajed Haque, Jeffrey Shallit
The discriminator of an integer sequence s = (s(i))_{i>=0}, introduced by Arnold, Benkoski, and McCabe in 1985, is the function D_s(n) that sends n to the least integer m such that…

Discriminators and k-Regular Sequences
Sajed Haque, Jeffrey Shallit
The discriminator of an integer sequence s = (s(i))_{i >=0}, introduced by Arnold, Benkoski, and McCabe in 1985, is the map D_s(n) that sends n >= 1 to the least positive integer m…
