Partial differential equations with supersymmetric (1, 1) time are inv
estigated by means of superspace Cauchy Kowalewsky and Cartan-Kahler t
echniques. Theorems for the existence and uniqueness of solutions are
found for a particular class of superanalytic functions. The (1, 1) ti
me evolution equations are very important in applications to supersymm
etric quantum mechanics and quantum field theory: the square roots of
Schrodinger and heat equations. We considered nonlinear analogs of the
se equations which can be interpreted as square roots of Maslov's nonl
inear Schrodinger and heat equations.
