Query: A Very Elementary Introduction to Sheaves   This paper is a very non-rigorous, loose, and extremely basic introduction to
sheaves. This is meant to be a a guide to gaining intuition about sheaves, what
they look like, and how they work, so that after reading this paper, someone
can jump into the extremely abstract definitions and examples seen in textbooks
with at least some idea of what is going on. Most of this material is inspired
and built from the work of Dr. Michael Robinson, and that of Dr. Robert Ghrist
and Dr. Jakob Hansen, as well as Dr. Justin Curry's PhD thesis, who are some of
the only applied sheaf theorists out there and they do an amazing job of
explaining sheaves in a concrete way through their research. The rest of this
paper is populated by mathematical definitions found in textbooks that I have
stretched from two lines into multiple pages, as well as some analogies for
thinking of sheaves I have thought of myself. This paper only assumes knowledge
of basic linear algebra, basic group theory, and the very fundamentals of
topology. If there is anything in the setup that you do not understand it is
probably a quick Wikipedia search away. I hope this paper provides insight,
intuition, and helpful examples of why sheaves are such powerful tools in both
math and science.
