Hi all, I was unsure where to put this thread as I read the main topic title in the topology/analysis forums and decided to post it here. I am looking for a chart/graph/website that helps me understand the basic terms such as: -neighborhoods -Boundary points -Singularity points - "Function is analytic" - "Function is entire - Function is harmonic and anything similar. My ultimate goal is to create some posters to hang up in my room based on the information to help me learn the terms. So for this, I need some well organized, to the point, material to work off of since I don't understand the terms currently. At best, I am hoping to find a visual understanding of the terms. If you have any good online resources please post them here. It's been difficult for me to find some via Google without really understanding the terms. Thanks.
