Gang Qian,Jiqing Zhang,Assegid Kidanénce, we find the sequences counting multicompositions with analogous restrictions. With these tools, we give combinatorial proofs of summation formulas for generalizations of the Jacobsthal and Pell sequences.

Extremal Sequences for Some Weighted Zero-Sum Constants for Cyclic Groups,so been found. After some introductory remarks, we here take up some questions regarding inverse problems related to the values of a weighted zero-sum constant for some particular weights for a finite cyclic group.

Infinite Co-minimal Pairs in the Integers and Integral Lattices,al pairs is a stronger criterion than the existence of minimal complements. In this work, we show several new results about them. The existence and the construction of co-minimal pairs in the integers, with both the subsets . and . (. is not a translate of .) of infinite cardinality was unknown. We

Bounds on Point Configurations Determined by Distances and Dot Products,e point set. Specifically, given a large finite set of . points ., we look for bounds on how many subsets of . points satisfy a set of relationships between point pairs based on distances or dot products. We survey some of the recent work in the area and present several new, more general families of
