Webb10 apr. 2024 · The celebrated Faber–Krahn inequality states that the lowest eigenvalue Λ 1 = Λ 1 (Ω) is minimized by a ball, among all sets of given volume. By the classical isoperimetric inequality, it follows that the ball is the minimizer under the perimeter constraint too. The optimality of the ball extends to repulsive Robin boundary conditions, …

WebbThe Poincare conjecture lies at the heart of modern geometry and topology, and even pertains to the possible shape of the universe. The conjecture states that there is only one shape possible for a finite universe in which every loop can be contracted to a single point. WebbTHE POINCARE CONJECTURE 5´ In particular, if M4 is a homotopy sphere, then H2 = 0 and κ = 0, so M4 is homeomorphic to S4. It should be noted that the piecewise linear or diﬀeren-tiable theories in dimension 4 are much more diﬃcult. It is not known whether every smooth homotopy 4-sphere is diﬀeomorphic to S4; it is not known which 4- openhands github
