	abstract = {Ly\${\textbackslash}alpha\$-emitting galaxies (LAEs) are easily detectable in the 
high-redshift Universe and are potentially efficient tracers of large
scale structure at early epochs, as long as their observed properties do
not strongly depend on environment. We investigate the luminosity and
equivalent width functions of LAEs in the overdense field of a
protocluster at redshift \$z {\textbackslash}simeq 3.78\$. Using a large sample of LAEs
(many spectroscopically confirmed), we find that the Ly\${\textbackslash}alpha\$
luminosity distribution is well-represented by a Schechter (1976)
function with \${\textbackslash}log(L{\textasciicircum}\{{\textbackslash}ast\}/\{{\textbackslash}rm erg s{\textasciicircum}\{-1\}\}) = 43.26{\textasciicircum}\{+0.20\}\_\{-0.22\}\$
and \${\textbackslash}log({\textbackslash}phi{\textasciicircum}\{{\textbackslash}ast\}/\{{\textbackslash}rm Mpc{\textasciicircum}\{-3\}\})=-3.40{\textasciicircum}\{+0.03\}\_\{-0.04\}\$ with
\${\textbackslash}alpha=-1.5\$. Fitting the equivalent width distribution as an
exponential, we find a scale factor of \${\textbackslash}omega=79{\textasciicircum}\{+15\}\_\{-15\}{\textbackslash}:
{\textbackslash}mathring\{A\}\$. We also measured the Ly\${\textbackslash}alpha\$ luminosity and equivalent
width functions using the subset of LAEs lying within the densest cores
of the protocluster, finding similar values for \$L{\textasciicircum}*\$ and \${\textbackslash}omega\$.
Hence, despite having a mean overdensity more than 2\${\textbackslash}times\$ that of the
general field, the shape of the Ly\${\textbackslash}alpha\$ luminosity function and
equivalent width distributions in the protocluster region are comparable
to those measured in the field LAE population by other studies at
similar redshift. While the observed Ly\${\textbackslash}alpha\$ luminosities and
equivalent widths show correlations with the UV continuum luminosity in
this LAE sample, we find that these are likely due to selection biases
and are consistent with no intrinsic correlations within the sample.
This protocluster sample supports the strong evolutionary trend observed
in the Ly\${\textbackslash}alpha\$ escape fraction and suggest that lower redshift LAEs
are on average significantly more dusty that their counterparts at
higher redshift.},
