〖 Δ〗_kl- Statistical Convergence via Neutrosophic Normed Spaces for Double Sequences

B. G. Ahmadu — 2025-03-01

In this paper, we present the extension of ∆-statistically convergent and ∆-statistically Cauchy sequences via neutrosophic normed space (NNS) to double sequences. The study in analogy also define and introduce for which lim or where denote set of all statistically convergent sequences. Furthermore, we present their feature utilizing double density and establish some inclusion relations between these concepts and prove some essentials analogous properties for double sequences.

Temperature Elliptic Sombor and Modified Temperature Elliptic Sombor Indices

V.R. Kulli — 2025-03-08

In this paper, we introduce the temperature elliptic Sombor index, modified temperature elliptic Sombor index and their corresponding exponentials of a graph. Also we compute these temperature indices for some standard graphs and HC₅C₇[p, q] nanotubes. Furthermore, we establish some properties of newly defined temperature elliptic Sombor index.

ON COMBINATORIAL IDENTITIES OF LUCAS AND FIBONACCI NUMBERS CONNECTED TO TCHEBYSHEV POLYNOMIALS

GOUTHAM C — 2025-03-12

The present paper is on derivation of many combinatorial identities of x_n = T_n (9), y_n = U_n-1 (9) , L_6n+k = L_k x_n +20 F_k y_n and F_6n+k = F_k x_n +4 L_k y_n , k=0,1,2,3,4,5 n=0,1,2,..., where T_n (x) and U_n-1 (x) are the well known Tchebyshev polynomials of first and second kind and L_n and F_n are the well known Lucas and Fibonacci numbers.

Implementation of Analytical Hierarchy Process (AHP) for Ranking Consumers Satisfaction Criteria in the Mathematics Dan Science Learning Center

Dwi Nur Yunianti — 2025-03-13

Customer satisfaction is defined as a measurement that determines the level of customer satisfaction with the products, services and capabilities of a service provider. In this article, we determine the priority order of criteria that influence the customer satisfaction in the mathematics and science learning center using the AHP method.

Based on the results of the AHP method, the main priority criterion is responsibility of providing information related to services with weight criterion is 0.216.
