Answers to two questions posed by Farhi concerning additive bases
Peter Hegarty
Let A be an asymptotic basis for N and X a finite subset of A such that A\X is still an asymptotic basis. Farhi recently proved a new batch of upper bounds for the order of A\X in…

Essentialities in additive bases
Peter Hegarty
Let A be an asymptotic basis for N_0 of some order. By an essentiality of A one means a subset P such that A¶is no longer an asymptotic basis of any order and such that P is minima…
