About This Design
Ricci Flow Solution Poincaré Conjecture (Geometry) Tie
No need to be a mathematician or physicist or topologist to enjoy any of these gifts featuring the Ricci flow, a kind of nonlinear diffusion equation. For the record, the Ricci flow (named after Gregorio Ricci-Curbastro) was introduced by Richard Hamilton in 1981 in order to gain insight into the geometrization conjecture of William Thurston, which concerns the topological classification of three-dimensional smooth manifolds. The Ricci flow plays an important role in Grigori Perelman's solution of the Poincaré conjecture. Memorable geometric gifts for any fan of geometric flows!

That's exactly what I was expecting! I made a custom design and it looks so good. I will definitely recommend this shop and service for my friends. Good quality. Exactly like in the photo.

The tie was shown as being black and white on the website but unfortunately it is green and white once I received it. This is false advertisement and I am reporting it. I want my money back. I'm willing to return the tie. It's no good. .

I was beyond thrilled with how this custom tie turned out. I applied my husband’s business name to it all over the place and it was beautifully produced, absolutely perfect. Silky, shiny, exactly as I designed it. The lettering was not raised which was my fear. It formed a part of the tie itself so it looked like it was supposed to be there! My husband loved it and I made 9 more in different designs. Produced very quickly, well packaged and arrived early! I loved this design so much!! The printing is not raised and the tie is silky smooth. It turned out exactly as I designed it!
