On Small Doubling in Right-Ordered Groups and Baumslag-Solitar Groups-II

Mohan, Neetu

Recently, Mohan et al. [Results Math. 80 (2025), No. 4, 122] answered Freiman's $3 k - 4$ conjecture in right-ordered groups under certain restrictions. In this paper, we take a step…

On additive complements in the complement of a set of natural numbers

Bhuwanesh Rao Patil, Mohan

Let $A$ be a set of natural numbers. A set $B$ , a set of natural numbers, is an additive complement of the set $A$ if all sufficiently large natural numbers can be represented in t…

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…

Freiman's $(3 k - 4)$ -like results for subset and subsequence sums

Mohan, Jagannath Bhanja, Ram Krishna Pandey

For a nonempty finite set $A$ of integers, let $S (A) = {\sum_{b \in B} b : \emptyset \neq = B \subseteq A}$ be the set of all nonempty subset sums of $A$ . In 1995, Nathan…

On additive complement with special structures

Mohan, Bhuwanesh Rao Patil, Ram Krishna Pandey

Let $A$ be a set of natural numbers. A set $B$ , a set of natural numbers, is said to be an additive complement of the set $A$ if all sufficiently large natural numbers can be repre…

Generalized H-fold sumset and Subsequence sum

Mohan, Ram Krishna Pandey

Let $A$ and $H$ be nonempty finite sets of integers and positive integers, respectively. The generalized $H$ -fold sumset, denoted by $H^{(r)} A$ , is the union of the sumsets $h^{(r)…

Extended inverse theorems for $h$ -fold sumsets in integers

Mohan, Ram Krishna Pandey

Let $h \geq 2$ , $k \geq 5$ be integers and $A$ be a nonempty finite set of $k$ integers. Very recently, Tang and Xing studied extended inverse theorems for $hk-h+1 < \left|hA\right…
