Title:Random Algebraic Geometry and Random Amoebas
****
**
**Abstract: Random algebraic geometry studies variable properties of 
typical algebraic varieties as opposed to invariant properties or 
extremal properties. For instance, a complex algebraic projective plane 
curve is always topologically connected, which is an invariant 
property;  a real algebraic projective plane curve of degree $d$ has, by 
a classical theorem of Harnack, at most $g+1=(d-1)(d-2)/2+1$ connected 
components where $g$ denotes genus, which is an extremal property; 
whereas a random real algebraic projective degree $d$ plane curve in a 
suitable precise sense (to be explained in the talk) has an expected 
number of connected components of order $d$. In this talk, I will first 
present the setup and some of the main known results of the field of 
random algebraic geometry. I will then proceed to discuss some of our 
results on the expected properties of amoebas of random complex 
algebraic varieties, based on a joint work with Turgay Bayraktar, and 
another joint work with Jean-Yves Welschinger.**
