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 geometrisation 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!

Very happy with 1) quality of the print 2) quality & cut of the tie 3) speed of manufacturing 4) communication & 5) delivery to UK. I discovered the product just 2 weeks before a wedding so had to use the express delivery but it arrived within days so I could relax. My first experience of this seller & Zazzle and both were great .

I wasn't sure what to expect but was excited to have a tie for my husband which matched my wedding attire. A super easy process taking a photo of my dress and uploading it to the website. I waited in anticipation not knowing how it would turn out. I couldn't believe the quality, its excellent. The print, pattern and colour is strong and vibrant.
I have uploaded a photo but its difficult to see the tie against the dress because the quality is exceptional. I would have no hesitation using this company again.
