Chaotic itinerancy as a new universal behavior in complex systems

In low-dimensional dynamical systems, the dynamical behavior is
classified into four
categories: a steady state, a periodic state, a quasi-periodic state,
and a chaotic state.
Each class of behavior is represented by a fixed point attractor, a
limit cycle, a torus, and a
strange attractor, respectively. However, the complex behavior in
high-dimensional
dynamical systems is not always described by these attractors. The more
ordered but more
complex than these types of behavior often appears. We have found one
such universal
behavior in nonequilibrium neural networks, globally coupled chaotic
systems, and optical
delayed systems. We called it a chaotic itinerancy. I would like to give
a talk on the recent
development of the research on chaotic itinerancy.

Maganhangzok es matematika (Vowel sounds and mathematics)

Eloadasomban a XVIII. szazad, pontosabban a francia felvilagosodas ket
filozofiai
vegpontjat szeretnem bemutatni, mely a maga modjan ad absurdum vitele -
ha ugy tetszik
logikailag legkonzekvensebb kifejtese - a maga elofelteveseinek. Az elso
a tudomanyos
gondolkodast - sot a racionalis reflexiot altalaban - az erkolcsok
megrontojakent kezelo
moralista felfogasa, Jean-Jacques Rousseau-e, aki a modernitas
kritikajat a
konyvnyomtatas, az irasbeliseg elveteseig, sot a zenei-maganhangzok
dominalta nyelvet
felvalto "elidegenedett" massalhangzok altal uralt nyelv
kulturkritikajaig fokozta. Elmeleti
ellenpolusa a matematikus-filozofus Condorcet, aki a Leibniz
kezdemenyezte
matematikai-logikai szimbolumrendszert nemcsak a termeszettudosok
nemzetekfolotti
kommunikacios eszkozenek tekintette, hanem a nemzeti elfogultsagokat, a
vallasi
eloiteleteket, az altudomanyos tevedeseket automatikusan kikuszobolo, s
ezzel az emberi
jogok egyetemesseget, a gondolat szabadsagat s az emberek eszbeli es
jogi egyenloseget
garantalo racionalista csodafegyvernek (avagy a racianalitas
vilagtortenelmi
hatalomatvetele garanciajanak). A fentemlitett vilagtortenelem fintora,
hogy Condorcet
kombinatorikajat a Rousseau megalmodta idealok - etnocentrikus allam,
idegengyuloletet
szentesito nemzeti vallas, teljhatalmu torvenyhozo - realizalasa
erdekeben mozgositotta,
azaz a matematizalt racionalitast az irracionalitas segedcsapatava
alazta.
