This study introduces ∗-reversible rings, a new class of algebraic structures with involutions. We explore their properties and find that polynomial extensions may not preserve this property, with minimal examples identified.
Area of Science:
- Abstract algebra
- Ring theory
- Commutative algebra
Background:
- Recent advancements in extended reversibilities on rings.
- The established properties of reversible, symmetric, reflexive, and semicommutative rings.
Purpose of the Study:
- To introduce and investigate ∗-reversible rings, a novel class of rings featuring involutions.
- To explore fundamental properties and provide illustrative examples of ∗-reversible rings.
- To determine conditions under which polynomial rings derived from ∗-reversible rings may not exhibit the ∗-reversible property.
Main Methods:
- Theoretical investigation of algebraic structures.
- Development of criteria for identifying rings that cannot accommodate involutions.
- Analysis of ring properties including symmetry, reflexivity, and semicommutativity.
Main Results:
- Demonstration that polynomial rings of ∗-reversible rings are not necessarily ∗-reversible.
- Establishment of a criterion for rings lacking the capacity to adhere to any involution.
- Identification of a minimal noninvolutary ring of order 4.
- Identification of a minimal noncommutative ∗-reversible ring of order 16.
Conclusions:
- ∗-reversible rings represent a significant extension within the study of reversible rings.
- The behavior of polynomial extensions and the existence of minimal examples provide key insights into the structure of these rings.

The statement can be further generalized to prove that entropy is a state function. Take a cyclic process between any two points on a p-V diagram.
