- Abstract: The Berezin--Simon (BS) quantization is a rigorous version of the ``operator
formalism'' of quantization procedure. The goal of the paper is to present a
rigorous real-time (not imaginary-time) path-integral formalism corresponding
to the BS operator formalism of quantization; Here we consider the classical
systems whose phase space $M$ is a (possibly non-compact) K\"ahler manifold
which satisfies some conditions, with a Hamiltonian $H:M\rightarrow\mathbb{R}$.
For technical reasons, we consider only the cases where $H$ is smooth and
bounded. We use G\"uneysu's extended version of the Feynman--Kac theorem to
formulate the path-integral formula.

Conditions [28.46014452281448]
It is necessary to use artificial boundary conditions (ABC) to confine quantum dynamics within a fixed domain.
The introduction of ABCs alters the Hamiltonian structure of the dynamics, and existing quantum algorithms can not be directly applied.
This paper utilizes a recently introduced Schr"odingerisation method that converts non-Hermitian dynamics to a Schr"odinger form.

We show that $r geq 2n/(n-2) can be acceptably quantized and the resulting theory is nontrivial, unlike what happens using canonical quantization.
In particular we consider the ultralocal $varphi4$ model and its renormalized properties for both the scaled canonical quantization and the scaled affine quantization version.

A strict deformation quantization is analysed on the classical phase space $bR2n$.
The existence of this classical limit is in particular proved for ground states of a wide class of Schr"odinger operators.
The support of the classical state is included in certain orbits in $bR2n$ depending on the symmetry of the potential.

We present a class of deformed creation and annihilation operators that originates from a rigorous notion of fuzziness.
This leads to deformed, sub-bosonic commutation relations inducing a simple algebraic structure with modified eigenenergies and Fock states.
In addition, we investigate possible consequences of the introduced formalism in quantum field theories, as for instance, deviations from linearity in the dispersion relation for free quasibosons.

Affine quantization is an alternative method, similar to the canonical quantization, that may offer a positive result in situations for which canonical quantization fails.
