Math Girls 6

Exploring the Poincaré Conjecture, this installment of the Math Girls series introduces readers to fundamental concepts of topology, starting with the historic Seven Bridges of Königsberg problem. Through the journey of Miruka and friends, readers encounter intriguing mathematical objects like the Möbius strip and Klein bottle, alongside essential topics such as homeomorphism, homotopy, and non-Euclidean geometries. The narrative also delves into differential equations, Fourier series, and concludes with Hamilton's Ricci flow, integral to Grigori Perelman's proof.
