DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NYNTS/4/">Po
 sitivity and negativity for additive h-bases for n</a>\nby Mel Nathanson (
 Lehman College (CUNY)) as part of New York Number Theory Seminar\n\n\nAbst
 ract\nA finite set $A$ of integers is an $h$-basis for $n$ if every intege
 r in the interval of integers \n$\\{0\,1\,2\,\\ldots\, n\\}$ can be repres
 ented as the sum of exactly \n $h$  not necessarily distinct elements of $
 A$.  \n In additive number theory\, attention has focused on sets of nonne
 gative integers\, \n but one can also consider sets that contain negative 
 integers and investigate  \n the effects of ``negativity'' on the classica
 l problem of extremal properties of $h$-bases for $n$.    \nThere are new 
 results and  a new class of problems \nfor additive bases that contain bot
 h positive and negative integers.\n
