Understanding fundamental group of realprojective space requires examining multiple perspectives and considerations. Realprojectivespace - Wikipedia. Real projective space has a natural line bundle over it, called the tautological bundle. More precisely, this is called the tautological subbundle, and there is also a dual n -dimensional bundle called the tautological quotient bundle.
algebraic topology - FundamentalGroup of $\mathbb {RP}^n .... In general, we can proceed inductively to find the fundamental group. The real projective space $\Bbb {RP}^n$ is homeomorphic to $D^n/ { (x\sim-x)}$ where $x\in\partial D^n\approx S^ {n-1}$.
Equally important, now, let $U$ be a smaller open $n$ -ball $\subset D^n$, then $\pi_1 (U)=1$. The Fundamental Group of the Real Projective Plane - Math3ma. The goal of today's post is to prove that the fundamental group of the real projective plane, is isomorphic to $\mathbb {Z}/2\mathbb {Z}$ And unlike our proof for the fundamental group of the circle, today's proof is fairly short, thanks to the van Kampen theorem! From another angle, real Projective Space: An Abstract Manifold.

In this talk, we seek to generalize the concept of manifold and discuss abstract, or topological, manifolds. We'll examine the example of real projective space, and show that it's a compact abstract manifold by realizing it as a quotient space. Math 601 Homework 3 Solutions to selected problems.
Show that the fundamental group of R3 f 0g is trivial, i.e., show that this space is simply connected. Hint: It may be helpful to approximate a loop in R3 f 0g by a polygonal loop. Furthermore, algebraic Topology I: Lecture 17 Real Projective Space. Summary: In real projective space, odd cells create new generators; even cells (except for the zero-cell) create torsion in the previous dimension. This example illustrates the significance of cellular homology, and, therefore, of singular homol-ogy.

From another angle, a CW structure involves attaching maps. Real projective space and the fundamental group. In relation to this, a) For the wedge product of spaces, you can use Van Kampen's Thm; for the cartesian product, there is a well-known property of fundamental group that gives you the answer directly (as you suggested, the product of two groups). Fundamental group - Wikipedia.
In the mathematical field of algebraic topology, the fundamental group of a topological space is the group of the equivalence classes under homotopy of the loops contained in the space. 13 - Fundamental Aspects of Real Projective Space.

Additionally, it seems there is a lot of difference between the computation of the real and the complex projective fundamental group without using homology, since I didn't have found any material on classical books either.
