Title: Towards infinite countable bifurcation trees of period-m to chaos in nonlinear dynamical systems with saddle-nodes
Abstract: In this talk, infinite bifurcation trees of periodic motions to chaos in in nonlinear dynamical systems with saddle-nodes are addressed.
The bifurcation trees of periodic motions to chaos in nonlinear dynamical systems is very significant for a better understanding of motion complexity. When a slowly varying excitation becomes very slow, the infinite bifurcation trees of period-1 motions to chaos in nonlinear dynamical systems can be achieved once the corresponding excitation amplitude approaches infinity. Towards infinite bifurcation trees in the Duffing oscillator and pendulum are discussed as examples.

Title: Fractional Calculus: Fundamentals, Concepts and Some Applications
Abstract: Fractional Calculus (FC) started in 1695 when L'Hopital wrote a letter to Leibniz asking for the meaning of Dny for n = 1/2. Starting with the ideas of Leibniz many important mathematicians developed the theoretical concepts. By the beginning of the twentieth century Olivier Heaviside applied FC in the electrical engineering, but, the visionary and important contributions were forgotten. Only during the eighties FC emerged associated with phenomena such as fractal and chaos and, consequently, in nonlinear dynamical. In the last years, FC become 'new' tool for the analysis of dynamical systems. This lecture introduces the FC fundamental concepts and presents several applications in distinct areas of science and engineering.

Title: Exponential and Related Non-Singular Memories: What is following after that in modelling technology?
Abstract: The recently appeared fractional operators with non-singular memory kernel described by exponential (Caputo-Fabrizio derivative) and generalized Mittag-Leffler function (Atangana-Baleanu derivative) raise many questions about their properties and mainly about their physical relevance and applications. This lecture focuses on the physics provoking creations of such fractional operators, compare their properties with the features of the well-known fractional operators with singular kernels and mainly, try to clarify what really we may models with them.

Title: On recent applications of non-integer order models to biological systems
Abstract: Research on fractional order (FO) models has suffered an extraordinary boost in the last few decades. The main reason is that FO models provide a more complete understanding of the complex dynamics of biological systems, than their integer order counterparts. In this talk, we will do a review on applications of FO models to biological systems, with emphasis to epidemiological models. We will discuss equilibria, stability of equilibria, reproduction number, and the role of the FO derivative in the epidemics' drama.
