In this paper we study some weighted Trudinger-Moser type problems, namely
s
F
,
h
=
sup
u
∈
H
,
‖
u
‖
H
=
1
∫
B
F
(
u
)
h
(
|
x
|
)
d
x
,
\begin{equation*} \displaystyle {s_{F,h} = \sup _{u \in H, \, \| u\|_H =1 } \int _{B} F(u) h(|x|) dx}, \end{equation*}
where
B
⊂
R
2
B \subset {\mathbb R}^2
represents the open unit ball centered at zero in
R
2
{\mathbb R}^2
and
H
H
stands either for
H
0
,
rad
1
(
B
)
H^1_{0, \textrm {rad}}(B)
or
H
rad
1
(
B
)
H^1_{\textrm {rad}}(B)
. We present the precise balance between
h
(
r
)
h(r)
and
F
(
t
)
F(t)
that guarantees
s
F
,
h
s_{F,h}
to be finite. We prove that
s
F
,
h
s_{F,h}
is attained up to the
h
(
r
)
h(r)
-radially critical case. In particular, we solve two open problems in the critical growth case.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
