Phys.org / Decades-old problem in classical geometry solved: First compact pair of bonnets found

For over 150 years, a rule of thumb dating back to the French mathematician Pierre Ossian Bonnet has been accepted in surface theory: If the metric and mean curvature of a compact surface are known at every point, then the ...
