Unique perfect matchings, forbidden transitions and proof nets for linear logic with Mix [PDF]

Logical Methods in Computer Science, 2020
This paper establishes a bridge between linear logic and mainstream graph theory, building on previous work by Retor\'e (2003). We show that the problem of correctness for MLL+Mix proof nets is equivalent to the problem of uniqueness of a perfect ...

Linking Off-Road Points to Routing Networks

Algorithms, 2022
Although graph theory has already been introduced in spatial reasoning, current spatial database systems do not provide out-of-the-box routing on geometric points that are not matched on the graph.

Structural matrices for Signed Petri net

AKCE International Journal of Graphs and Combinatorics, 2022
The developments in the field of Graph Theory and Petri net Theory in the form of balanceness and negative tokens respectively motivated the authors to bridge the gap between Petri net and Signed graph and introduce a new concept of Signed Petri net (SPN)

On Generalized Topological Indices for Some Special Graphs

Journal of Mathematics, 2022
Topological indices are numeric values associated with a graph and characterize its structure. There are various topological indices in graph theory such as degree-based, distance-based, and counting-related topological indices.

Certain Notions of Picture Fuzzy Information with Applications

Journal of Mathematics, 2021
In this manuscript, the theory of constant picture fuzzy graphs (CPFG) is developed. A CPFG is a generalization of constant intuitionistic fuzzy graph (CIFG) and a special case of picture fuzzy graph (PFG).

Placing Green Bridges Optimally, with a Multivariate Analysis [PDF]

Theory Comput. Syst. (2024), 2021
We study the problem of placing wildlife crossings, such as green bridges, over human-made obstacles to challenge habitat fragmentation. The main task herein is, given a graph describing habitats or routes of wildlife animals and possibilities of building green bridges, to find a low-cost placement of green bridges that connects the habitats.
