We describe q-deformation of the extended supersymmetry and construct
q-extended supersymmetric Hamiltonian. For this purpose we formulate q
-superspace formalism and construct q-supertransformation group. On th
is basis q-extended supersymmetric Lagrangian is built. The canonical
quantization of this system is considered. The connection with multi-d
imensional matrix representations of the parasupersymmetric quantum me
chanics is discussed and q-extended supersymmetric harmonic oscillator
is considered as a simplest example of the described constructions. W
e show that extended supersymmetric Hamiltonians obey not only extende
d SUSY but also the whole family of symmetries (q-extended supersymmet
ry) which is parametrized by continuous parameter q on the unit circle
.
