Get taxonomy value name

I have a blog with a custom taxonomy called “authors”.
On the homepage a list of all “authors” values are displayed (eg: Mark, Paul, John, etc.) using the following script:

$terms = get_terms("autors");
$count = count($terms);
if ( $count > 0 ){
echo '<ul>';
foreach ( $terms as $term ) {
echo '<li> <a href="/autors/' . $term->slug . '" title="' . sprintf(__('View all post filed under %s', 'my_localization_domain'), $term->name) . '">' . $term->name . '</a> </li>';
}
echo '</ul>';
}

Each author name is permalinked with his url to display posts of that author.
For example:

• Mark
• Luke
• John

When I click them I get redirected to the archive page containing the post of that author.
I don’t want this. I simply want to get the author name.
So:

• How can I prevent the archive page from being displayed?
• How can I get the author name?
  For example: if I’m on the page http://www.test.com/autors/mark, I want to get *$author_name = mark*;

Can you help me, please?
Thank you
