초록 : We will introduce finiteness theorems for representability
of Hermitian lattices over imaginary quadratic field $\mathbb{Q}(\sqrt{-m})$.
One is a criterion on universality of Hermitian lattices over
$\mathbb{Q}(\sqrt{-m})$. Another is a criterion on even universality of
Hermitian lattices over $\mathbb{Q}(\sqrt{-m})$ which admit even universal
binary Hermitian lattices. Finally, we apply these results to the Kloosterman
problem and provide a Bochnak-Oh type criterion for almost universal binary
Hermitian.
