Sinhronizacija v dinamičnih sistemih in kompleksnih mrežah ter njena uporaba

 

Sinhronizacija se pogosto pojavlja v naravi, tehnologiji in v družabnem
življenju, npr. pri piščalih orgel, kresničkah in celo pri mehaniki mostov.
Prvi jo je opazil Christiaan Huygens l. 1665 pri sklopljenih urnih nihalih;
to je bil začetek nelinearne znanosti. V zadnjih dveh desetletjih se je ta
koncept razširil na kompleksne sisteme, kot so sklopljeni kaotični
oscilatorji in celo prostorsko porazdeljeni sistemi, npr. kompleksne mreže.
Kompleksne mreže je prvi raziskoval Leonhard Euler l. 1736, ko se je lotil
znanega problema mostov v Königsbergu. Nedavne raziskave so razkrile bogato
in zapleteno topologijo mrež v različnih modelskih sistemih ter na več
področjih uporabe, kot so transportna in družabna omrežja ter svetovni
splet. Opisali bomo sinhronizacijo v aktivnih kompleksnih mrežah. Poročali
bomo o napredku pri razumevanju sinhronizacije v primeru, ko so nihajoči
elementi lahko interagirajo le znotraj kompleksne topologije mreže.
Predstavili bomo tudi novo obnašanje, ki izhaja iz strukture in funkcije
vzorcev povezav. Klasično lokalna stabilnost dinamičnih mrež bomo primerjali
z novim konceptom bazena stabilnosti. Naposled bomo orisali nekaj primerov
uporabe sinhronizacije kompleksnih mrež od človeških možganov do električnih
omrežij in podnebja.

Predavanje bo v angleščini.

Lepo vabljeni!

Synchronization in Dynamical Systems and Complex Networks and its
Applications

 

Synchronization phenomena are abundant in nature, science, engineering and
social life, such as in organ pipes, fireflies and even in the mechanics of
bridges. But synchronization was first recognized by Christiaan Huygens in
1665 for coupled pendulum clocks; this was the beginning of nonlinear
sciences. In the last two decades, this concept has been successfully
extended to more complex systems, as coupled chaotic oscillators and even
distributed systems as complex networks. Complex networks were first studied
by Leonhard Euler in 1736 when he solved the Königsberger Brückenproblem.
Recent research has revealed a rich and complicated network topology in
various model systems as well as in several fields of applications, such as
transportation and social networks, or the WWW. We will discuss
synchronization phenomena on active complex networks. We will report the
advances in the comprehension of synchronization phenomena when oscillating
elements are constrained to interact in a complex network topology. We will
also present new emergent features coming out from the interplay between the
structure and the function of the underlying patterns of connections. The
classic local stability in dynamic networks is compared to the new basin
stability concept. Finally, several applications of synchronization in
complex networks from human brain via power grids to climate are given.
