Are context-sensitive languages recognizable by a Turing Machine?
Context-sensitive languages (CSLs) are a class of formal languages that are defined by context-sensitive grammars. These grammars are a generalization of context-free grammars, allowing production rules that can replace a string with another string, provided the replacement occurs in a specific context. This class of languages is significant in computational theory as it is more
Is PSPACE class not equal to the EXPSPACE class?
The question of whether the PSPACE class is not equal to the EXPSPACE class is a fundamental and unresolved problem in computational complexity theory. To provide a comprehensive understanding, it is essential to consider the definitions, properties, and implications of these complexity classes, as well as the broader context of space complexity. Definitions and Basic

Is P complexity class a subset of PSPACE class?
In the field of computational complexity theory, the relationship between the complexity classes P and PSPACE is a fundamental topic of study. To address the query regarding whether the P complexity class is a subset of the PSPACE class or if both classes are the same, it is essential to consider the definitions and properties
Are there problems in PSPACE for which there is no known NP algorithm?
In the realm of computational complexity theory, particularly when examining space complexity classes, the relationship between PSPACE and NP is of significant interest. To address the question directly: yes, there are problems in PSPACE for which there is no known NP algorithm. This assertion is rooted in the definitions and relationships between these complexity classes.
