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…

Inverse problems for certain subsequence sums in integers

Jagannath Bhanja, Ram Krishna Pandey

Let $A$ be a nonempty finite set of $k$ integers. Given a subset $B$ of $A$ , the sum of all elements of $B$ , denoted by $s (B)$ , is called the subset sum of $B$ . For a nonnegative i…

Direct and inverse results on restricted signed sumsets in integers

Jagannath Bhanja, Takao Komatsu, Ram Krishna Pandey

Let $G$ be an additive abelian group. Let $A = {a_{0}, a_{1}, \dots, a_{k - 1}}$ be a nonempty finite subset of $G$ . For a positive integer $h$ satisfying $1 \leq h \leq k$ , we let \[h…
