dihedral

I think a two wing version with the same dihedral angle would be just as stable.

Thus, the dihedral effect is weak and the wing will not rise to the level position.

Check out page 126 of Stick And Rudder for an intuitive illustration of why dihedral works.

It's essentially a dihedral effect like that of an airplane.

We call these secondary structure elements, and they are limited by phi and psi angles on the dihedral C-N peptide bond.

Are there wing designs that encompass strong dihedral characteristics?

I first learn group in abstract, then I study dihedral group, symmetry groups etc... If done the other way around I'm always confused as to what are rules of the game.

The standard way to "solve" this problem is to define "dummy atoms", fictitious sites that are only used to construct well-defined bending and dihedral angles.

No discussion of the dihedral groups, hamiltonian groups, stabilizers, kernels, group actions, etc...The rubics cube solution at the end is interesting though.

Whereas factoring reduces to the abelian hidden subgroup problem, which is solvable in quantum polynomial time, SVP is only known to reduce to the dihedral hidden subgroup problem, which is not known to be solvable in quantum polynomial time despite a decade of effort.> Inspired by this observation, and building on earlier work by Ajtai and Dwork, Oded Regev has recently proposed public-key cryptosystems that are provably secure against quantum eavesdroppers, assuming SVP is hard for quantum computers.
