pub_http_internet directory has all the read permissions disabled?Your public website resides in your network account in the subdirectory pub_http_internet. All files located there can be accessed by a web browser. Your personal homepage should be in a file called index.html. You can also put additional files in that subdirectory, and you can link to them from your index.html using HTML syntax. (You'll probably want to learn a little about HTML, or you might get away with just using a GUI editor.)
After setting up your personal webpages, to active the "Homepage" link in the department people list, please contact the computer support staff.

pub_http_internet directory has all the read permissions disabled?Short answer: The default setup for new accounts grants the minimum permissions necessary for your webpages to be accessible. To decide whether you want to grant additional permissions, see the longer answer below.
Prerequisite: To understand the following longer answer, you should know a little about Unix file permissions. In short, each file and each directory carries separate read/write/execute permissions for you, for members of your group, and for all other users (the latter category includes the public webserver). You see these permissions when you issue the command ls -l. For files, the meaning of the permissions is self-explanatory. For directories, the permissions have special meanings: read permission is the right to see a listing of the directory contents, write permission is the right to create new files/directories or delete files/directories inside the given directory, and execute permission is the right to attempt to access (read or write contents of) files inside the given directory; whether the latter succeeds furthermore depends on whether the file in question has appropriate permissions set.
For your public webpages in pub_http_internet to be accessible, at a minimum both your home directory and the directory pub_http_internet must have execute permission granted to other (non-owner and non-group) users. This minimum requirement lets people reach webpages if they know the URL of the page.
If you grant read permission on pub_http_internet, and if you furthermore delete your index.html file, then web browsers pointed at your home page URL will see a directory listing instead of an error message. Many users consider this a good thing. To grant this directory read permission, issue the commands:
cd chmod go+r pub_http_internetTo remove this permission, issue the commands:
cd chmod go-r pub_http_internet
(By the way: The execute permission on your home directory, which is necessary for your webpages to work, unfortunately also allows fellow users within the math department to access files inside your home directory if they know the name of the file and if the file gives read permission to group or others. To keep other users out of your home directory, ensure that your private files have read permission only for yourself. A simple trick is to put all your private files inside subdirectories that give read/write/execute permission only to yourself---then it makes no difference what permissions the files inside those subdirectories have.)
The department does not maintain a list of research projects; instead, there is a listing of faculty areas of interest, and each research area links to a brief description which may optionally include a link to a separate website maintained by that research group. If your research project fits into one or more groups, please contact those groups to get the project listed on the group's webpages. If your project does not fit into an existing research group, please contact the department head if you feel the list of research groups needs to be amended.
