  The electronic behavior in graphene under arbitrary uniaxial deformations,
such as foldings or flexural fields is studied by including in the Dirac
equation pseudoelectromagnetic fields. General foldings are thus studied by
showing that uniaxial deformations can be considered pseudomagnetic fields in
the Coulomb gauge norm. This allows to give an expression for the Fermi (zero)
energy modes wavefunctions. For random deformations, contact is made with
previous works on the quantum Hall effect under random magnetic fields, showing
that the density of states has a power law behavior and that the zero energy
modes wavefunctions are multifractal. This hints at an unusual electron
velocity distribution. Also, it is shown that a strong Aharonov-Bohm
pseudo-effect is produced. For more general non-uniaxial general flexural
strain, it is not possible to use the Coulomb gauge. The results presented here
helps to tailor-made graphene uniaxial deformations to achieve specific
wavefunctions.
