DESCRIPTION:Rumours are an important from of social communicat
ions and their spreading plays a significant role
in a variety of human affairs. In this talk I wil
l give an overview of our ongoing research on theo
ry and modelling of rumour spreading in complex so
cial networks. A general mathematical model for th
e spreading of stochastic rumours on large social
networks is introduced and the critical properties
and spreading dynamics of rumours on several mode
ls of social networks\, including random graphs\,
scale-free networks\, small world networks and ran
dom geometric graphs are investigated via a combin
ation of mathematical modelling and numerical simu
lations. Finally\, the impact of l correlations an
d clustering on the dynamics of rumour spreading a
re studied. Some initial results on modelling corr
uption contagion in organizational networks will b
e presented. \n \nSee also the following publica

ovee\n\nBio: Dr. Maziar Nekovee is a Senior Scient
ist at BT Research and an Honorary Senior Fellow a
t University College London. He received his MSc.
in Electrical Engineering (cum laude) from Delft U
niversity of Technology in the Netherlands and his
PhD in theoretical Physics from the University of
Nijmegen\, also in the Netherlands. Dr Nekovee’s
research cuts across several science and engineeri
ng disciplines and involves collaborations with st
atistical physicists\, applied mathematicians\, ma
nagement scientists and computer scientists. His c
urrent research focuses on theory\, mathematical m
odelling and applications of complex networked sys
tems\, including social networks\, computer networ
ks and wireless telecommunication networks. Dr Ne
kovee is the recipient of a prestigious Industry F
ellowship from the Royal Society. His new book on
“Cognitive Radio Communication and Networks: Prin
ciple and Practice” was published recently by Els
evier/Academic Press.
