Some direct and inverse problems for the Restricted Signed sumset in set of integers

Mohan, Raj Kumar Mistri, Ram Krishna Pandey

Given a positive integer $h$ and a nonempty finite set of integers $A = {a_{1}, a_{2}, \dots, a_{k}}$ , the restricted $h$ -fold signed sumset of $A$ , denoted by $h_{\pm}^{\land} A$ , i…
