On capitulations of even -groups and pseudo-null submodules in -extensions

Meng Fai Lim

The capitulations of ideals in -extensions and pseudo-null submodules of the classical Iwasawa modules are closely related as evidenced in the works of Ozaki and Fu…

On the structure of fine Mordell-Weil groups over a -extension and its intermediate subextensions

Meng Fai Lim

In this paper, we investigate the structure of the fine Mordell-Weil groups over the intermediate subextensions of a given -extension of .

On Iwasawa theory of abelian varieties over -extension with applications to Diophantine stability and integally Diophantine extensions

Meng Fai Lim

We present certain results on the Iwasawa theory of an abelian variety with potentially good ordinary reduction at all primes above . These are then applied to study Diophantine…

Algebraic functional equation for big Galois representations over multiple -extensions

Zeping Hao, Meng Fai Lim

We present a general approach to establish algebraic functional equations for big Galois representations over multiple -extensions. Our result is formulated in both S…

Comparing direct limit and inverse limit of even -groups in non-commutative -adic Lie extensions

Meng Fai Lim

In a previous paper of the author, we establish a duality for the direct limit and the inverse limit of higher even -groups over a -extension. In this paper, we…

On the -divisibility of even -groups of the ring of integers of a cyclotomic field

Meng Fai Lim

Let be a given positive odd integer and an odd prime. In this paper, we shall give a sufficient condition when a prime divides the order of the groups $K_{2k}(\mathbb{Z…
