Maximal density and the kappa values for the families and
Ram Krishna Pandey, Neha Rai
Let be a set of positive integers. We study the maximal density of the sets of nonnegative integers whose elements do not differ by an element in . In 1973, Canto…
Inverse problems for certain subsequence sums in integers
Jagannath Bhanja, Ram Krishna Pandey
Let be a nonempty finite set of integers. Given a subset of , the sum of all elements of , denoted by , is called the subset sum of . For a nonnegative i…

Jagannath Bhanja, Takao Komatsu, Ram Krishna Pandey
Let be an additive abelian group. Let be a nonempty finite subset of . For a positive integer satisfying , we let \[h…
Direct and Inverse Theorems on Signed Sumsets of Integers
Jagannath Bhanja, Ram Krishna Pandey
Let be an additive abelian group and be a positive integer. For a nonempty finite subset of , we let \[h_{\underline{+}}A:=\{Σ_{i=0}^{k-…
