Titre: "Mixed joint universality for zeta-functions"
"The Riemann zeta-function has the universality
property, that is, roughly, it approximates any holomorphic
function on a given compact set. Now it is known that many other
zeta and $L$-functions satisfy the same property. Under some
suitable conditions, simultaneous (or "joint") universality among
several zeta-functions also holds. In particular, the joint
universality between a zeta-function with Euler product and
another zeta-function without Euler product, first discovered by
H. Mishou, is called the mixed joint universality. In this talk
we will discuss how general the mixed joint universality holds.
(This is a joint work with R. Kacinskaite.)"
