Computing the set of asymptotic critical values of polynomial mappings from smooth algebraic sets
Let $\mathbf{f} = (f_1, \dots, f_p) \in \mathbb{Q}[z_1, \dots, z_n]$ be a polynomial tuple. Define the polynomial mapping $\mathbf{f}: X \to \mathbb{C}^p$, where $X$ is a smooth algebraic set defined by the simultaneous vanishing of the reduced regular ...

M-polynomial and topological indices of zigzag edge coronoid fused by starphene
Chemical graph theory is a subfield of graph theory that studies the topological indices for chemical graphs that have a good correlation with chemical properties of a chemical molecule.

Uniform Bahadur Representation for Local Polynomial Estimates of M-Regression and Its Application to The Additive Model [PDF]
We use local polynomial fitting to estimate the nonparametric M-regression function for strongly mixing stationary processes {(Yi,Xi)}. We establish a strong uniform consistency rate for the Bahadur representation of estimators of the regression ...

M-polynomial revisited: Bethe cacti and an extension of Gutman’s approach [PDF]
The $M$-polynomial of a graph $G$ is defined as $\sum_{i\le j} m_{i,j}(G)x^iy^j$, where $m_{i,j}(G)$, $i,j\ge 1$, is the number of edges $uv$ of $G$ such that $\{d_v(G), d_u(G)\} = \{i,j\}$. Knowing the $M$-polynomial, formulas for bond incident degree indices (an important subclass of degree-based topological indices) can be obtained by means of ...

Topological Characterization of the Third Type of Triangular Hex-derived Networks
A topological index is a numerical quantity that defines a chemical descriptor to report several physical, biological and chemical properties of a chemical structure. In recent literature, various degree-based topological indices of a molecular structure

M-Polynomial and Degree Based Topological Indices of Some Nanostructures [PDF]
The association of M-polynomial to chemical compounds and chemical networks is a relatively new idea, and it gives good results about the topological indices. These results are then used to correlate the chemical compounds and chemical networks with their chemical properties and bioactivities.

The M-polynomial of line graph of subdivision graphs
Summary: Three composite graphs Ladder graph \((L_n)\), Tadpole graph \((T_{n,k})\) and Wheel graph \((W_n)\) are graceful graphs, which have different applications in electrical, electronics, wireless communication etc. In this report, we first determine \(M\)-polynomial of the Line graph of those three graphs using subdivision idea and then compute ...

In this paper, we give and study the concept of n-polynomial ( s , m ) $(s,m)$ -exponential-type convex functions and some of their algebraic properties. We prove new generalization of Hermite–Hadamard-type inequality for the n-polynomial ( s , m ) $(s,m)

M-Polynomials and Topological Indices of Dominating David Derived Networks
There is a strong relationship between the chemical characteristics of chemical compounds and their molecular structures. Topological indices are numerical values associated with the chemical molecular graphs that help to understand the physical features,
