 Abstract : In this talk, I will explain the latter half part of the paper
of SkinnerUrban, ‘‘The Iwasawa main conjecture for $GL_{2}$’’.
Let $G = GU(2, 2)$ be the unitary similitude group of
the vector space with a skew Hermitian paringover an imaginary
quadratic field. I will talk about how they constructed $p$adic
analytic family of Klingentype Eisenstein series on $G$
whose Fourier coefficients at singular matrices are
divisible by the threevariable $p$adic $L$function.
