Hosoya Polynomials of Generalized Vertex Identified and Edge Introducing Graphs [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2013 The vertex identified and edge introducing graphs of two disjoint connected graphs are extended to n, , disjoint connected graphs. Hosoya polynomials and Wiener indices of such composite graphs are obtained by applying Gutman's Theorem and using ...

Time complexity and gate complexity
, 2010 We formulate and investigate the simplest version of time-optimal quantum computation theory (t-QCT), where the computation time is defined by the physical one and the Hamiltonian contains only one- and two-qubit interactions.

Hamiltonian structure and quantization of 2+1 dimensional gravity coupled to particles [PDF]
, 2000 It is shown that the reduced particle dynamics of 2+1 dimensional gravity in the maximally slicing gauge has hamiltonian form. This is proved directly for the two body problem and for the three body problem by using the Garnier equations for ...

Numerical Solution of Volterra-Fredholm Integral Equations with Hosoya Polynomials
Mathematical Methods in the Applied Sciences, 2021 In this study, Volterra-Fredholm integral equation is solved by Hosoya Polynomials. The solutions obtained with these methods were compared on the figure and table. And error analysis was done. Matlab programming language has been used to obtain conclusitions, tables and error analysis within a certain algorithm.

Computing Wiener and Hyper-Wiener Indices of Zero-Divisor Graph of ℤℊ3×ℤI1I2
Journal of Function Spaces, 2022 Let S=ℤℊ3×ℤI1I2 be a commutative ring where ℊ,I1 and I2 are positive prime integers with I1≠I2. The zero-divisor graph assigned to S is an undirected graph, denoted as YS with vertex set V(Y(S)) consisting of all Zero-divisor of the ring S and for any c,

Towards Practical Typechecking for Macro Tree Transducers [PDF]
, 2007 Macro tree transducers (mtt) are an important model that both covers many useful XML transformations and allows decidable exact typechecking. This paper reports our first step toward an implementation of mtt typechecker that has a practical efficiency ...

Hosoya-Diudea polynomial in hyper structures
Acta Chemica Iasi, 2013 Abstract Hosoya polynomial counts finite sequences of distances in a graph G; more exactly, it counts the number of points/atoms lying at a given distance in G. The polynomial coefficients are calculable by means of layer/shell matrices. Shell matrix operator enables the transformation of any square matrix in the corresponding layer/shell matrix ...

Complexity, Volume 2025, Issue 1, 2025.Nanomaterials find application in electronics, drugs, and biology among other disciplines. Benzenoid systems with their homogeneous structures are especially fit for computer study because of their predictable geometries. This work investigates computational analysis of benzenoid systems using valency‐based entropy measurements and degree‐based ...

Hosoya polynomial of a multi-bridge graph
, 2021 Explicit expressions of the Hosoya polynomials of some classes of graphs are known. In this paper we find an explicit expression for the Hosoya polynomial of the multibridge graph. Finally we give some examples of multi-bridge graphs which are chemical graphs.
