“…At a glance, we can see that the WDW equation is static, this can be understood as the problem of time in standard quantum cosmology. We can avoid this problem by measuring the physical time with respect a kind of time variable anchored within the system, that means that we could understand the WDW equation as a correlation between the physical time and a fictitious time [26,27].…”

“…The last ideas are the basis of the canonical quantization and the equation HΨ = 0 is known as the WDW equation. This equation is a second-order differential equation on superspace, which means we have one differential equation in each hypersurface of the extended space-time (for more details see [26,27]). On the other hand, the WDW equation has factor-ordering ambiguities, and the derivatives are the Laplacian in the supermetric G [27].…”

“…The term ℓ is the dynamical variables of the minisuperspace which are ℓ = , . This formalism is known as Bohm's formalism too [27,[32][33][34]. So, (49a) is transformed under expression (59) into…”

“…On the other hand, the relation between SFD and other symmetries has been pointed in the past (see 7 ), namely supersymmetry, therefore including anticommuting variables in the corresponding minisuperspace configuration or phase space, by means or taking at the start an action based, e.g., on a (albeit simplified) supergravity setting. We can say that our guiding target is to establish a robust correspondence involving minisuperspace symmetries (for bosonic and fermionic degrees of freedom) and subsequently allowing to specify how and which boundary conditions can be suggested to select.…”

“…A key element for the development of the present work is the interesting fact that closed string tachyons, which are nonsupersymmetric in the target space, can have worldsheet supersymmetry [2]. Supersymmetric cosmology has been studied in a variety of different schemes, we refer the interested reader to the well known books by D'Eath and Moniz for a review [3,4]. In [5] a Lagrangian of supersymmetric tachyons in the framework of a FRW background was given in a worldline superspace where, the time variable is extended to the superspace of supersymmetry [6,7], this is done considering the covariant formulation of one-dimensional supergravity of the so called 'new' Θ variables [8,9], which allows in a straightforward way to write supergravity invariant actions.…”
