Hockey-Stick Domination and Distributional Comparison on Finite Posets

Arturo Jaramillo, Saylé Sigarreta

We develop a framework for comparing probability measures on finite posets via hockey-stick domination, an order relation defined through interval-counting test functions. The theo…

Extremal degree-based indices of general polyomino chains via dynamic programming

Manuel Montes-y-Morales, Sayle Sigarreta, Hugo Cruz-Suarez

In this paper, we develop a dynamic programming framework for identifying extremal general polyomino chains with respect to degree-based topological indices. As a concrete applicat…

Maximum augmented Zagreb index on polyomino chains

Manuel Montes-y-Morales, Saylé Sigarreta, Hugo Cruz-Suárez

In this paper, we present a dynamic programming approach for identifying extremal polyomino chains with respect to degree-based topological indices. This approach provides an expli…

Third Order Cumulants of products

Octavio Arizmendi, Daniel Munoz George, Saylé Sigarreta

We provide a formula for the third order free cumulants of products as entries. We apply this formula to find the third order free cumulants of various Random Matrix Ensambles incl…

Degree Based Topological Indices of a General Random Chain

Sayle Sigarreta, Hugo Cruz-Suarez, Sergio Torralbas Fitz

In this paper, we examine a specific type of random chains and propose an unified approach to studying the degree-based topological indices, including their extreme values. We deri…
