Sumsets with a minimum number of distinct terms

Jagannath Bhanja

For a set $A$ of $k$ elements from an additive abelian group $G$ and a positive integer $r \leq k$ , we consider the set of elements of $G$ that can be written as a sum of $h$ eleme…

An improved threshold for the number of distinct intersections of intersecting families

Jagannath Bhanja, Sayan Goswami

A family $F$ of subsets of ${1, 2, \dots, n}$ is called a $t$ -intersecting family if $∣ F \cap G ∣ \geq t$ for any two members $F, G \in F$ and for some positive i…

A note on distinct differences in $t$ -intersecting families

Jagannath Bhanja, Sayan Goswami

For a family $F$ of subsets of ${1, 2, \dots, n}$ , let $D (F) = {F ∖ G : F, G \in F}$ be the collection of all (setwise) differences…

A Note on Sumsets and Restricted Sumsets

Jagannath Bhanja

In this note we find the optimal lower bound for the size of the sumsets $H A$ and $H^A$ over finite sets $H, A$ of nonnegative integers, where $H A = ⋃_{h \in H} h A$ and…
