This study establishes quantum mechanics operator relations on nilpotent Lie groups, deriving novel inequalities with best constants for momentum, position, and potentials. These findings advance understanding in quantum mechanics, particularly for anisotropic and Heisenberg group settings.
Area of Science:
- Quantum Mechanics
- Lie Groups
- Mathematical Physics
Background:
- Quantum mechanics operators govern physical systems.
- Nilpotent Lie groups provide a general framework for studying symmetries.
- Homogeneous groups are a key class within Lie groups.
Purpose of the Study:
- To establish relations between fundamental quantum mechanical operators.
- To derive analogues of established inequalities on homogeneous groups.
- To obtain best constants for these derived inequalities.
Main Methods:
- Utilizing operator relations on general classes of nilpotent Lie groups.
- Applying methods to homogeneous groups, including isotropic and anisotropic settings.
- Deriving Hardy's, Heisenberg-Kennard, Heisenberg-Pauli-Weyl, and Caffarelli-Kohn-Nirenberg inequalities.
Main Results:
- New relations between momentum, position, Euler, and Coulomb potential operators are presented.
- Best constants for derived inequalities are determined.
- Novel results are achieved for isotropic, anisotropic, and Heisenberg group settings.
Conclusions:
- The established operator relations provide a foundation for further quantum mechanical studies.
- The derived inequalities and their best constants offer significant advancements.
- The proof methodology is robust for both isotropic and anisotropic scenarios.

Routh-Hurwitz Criterion II
The first scenario occurs when a singular zero appears in the first column of the Routh table. This situation creates a division by zero issues. To resolve this, a small positive or negative number, denoted as epsilon (∈), is substituted for the zero. The stability analysis proceeds by assuming a sign for ∈. If ∈ is positive, any sign change in the first...
