Stability conditions for functional differential equations can be obtained using Lyapunov
functionals. Lyapunov Functionals and Stability of Stochastic Functional Differential …

The pivotal aim of the present work is to obtain an approximated analytical solution for the
fractional smoking epidemic model with the aid of a novel technique called q-homotopy …

Mathematical epidemiology has a long history of origin and development. In particular,
mathematical modeling and analysis of infectious diseases has become a fundamental and …

Several experimental studies have found that obesity is a risk factor for different types of
cancer. In this work we present a mathematical model of cancer tumor growth that takes into …

We obtain an approximated analytical solution for a dynamic model for the prevalence of the
smoking habit in a constant population but with equal and different from zero birth and death …

In this paper, we investigate, by means of a Spatial Markov Chains approach, the existence
of proximity effects at State level for US data on obesity rates in the period 1990–2011. We …

The primary goal of the current work is to use a novel technique known as the natural
transform decomposition method to approximate an analytical solution for the fractional …

Excess weight is fast becoming a serious health concern in the developed and developing
world. The concern of the public health sector has lead to the development of public health …

The work in this paper focuses on solving numerically and analytically a nonlinear social
epidemic model that represents an initial value problem of ordinary differential equations. A …

The excess weight population is growing riskily in Spain. This is confirmed by the Spanish
National Health Survey 2017, which gathers the percentage of overweight and obese adults …
