Pingala's work on prosody and combinatorics is known as Chandas Shastra, which is considered one of the earliest works on these subjects.

Pingala's Chandas Shastra primarily focuses on prosody and meter, providing rules and techniques for composing Sanskrit poetry in various meters.

Pingala's Chandas Shastra is significant for providing a comprehensive theory of Sanskrit prosody, including the classification of poetic meters, the rules for their construction, and the analysis of their rhythmic patterns.

Pingala introduced the concept of combinatorial analysis, which involves counting and arranging objects in different ways. This concept is considered a precursor to modern combinatorics.

Pingala derived the formula $$C(n, r) = n! / r!(n-r)!$$ for calculating the number of combinations of 'n' objects taken 'r' at a time, which is known as the combination formula.

Pingala's work in combinatorics is significant for providing a systematic approach to counting and arranging objects, which laid the foundation for the development of modern combinatorics.

Pingala is credited with inventing the Vasantatilaka poetic meter, which is characterized by its unique rhythmic pattern and is considered one of the most complex meters in Sanskrit poetry.

The Vasantatilaka meter is considered the most difficult meter to master in Sanskrit poetry due to its complex rhythmic pattern and the skill required to compose poetry in this meter.

Pingala used the mathematical concept known as Ganita-sara-samgraha to analyze poetic meters. This concept involves the use of mathematical techniques to study the rhythmic patterns and structures of poetry.

Pingala's work in mathematics is significant for providing a systematic approach to solving mathematical problems, particularly in the areas of prosody and combinatorics.

Pingala used a mathematical technique called Vrtta-matra-ganana to count the number of possible combinations of poetic syllables in different meters.

Pingala's work in linguistics is significant for providing a systematic approach to analyzing language, particularly in the areas of prosody and meter.

Pingala introduced the linguistic concept of Svara-gana to analyze the structure of poetic language, which involves the classification of syllables based on their phonetic properties.

Pingala's work in literature is significant for providing a systematic approach to analyzing literature, particularly in the areas of prosody and meter.

Pingala introduced the literary concept of Pada-chhanda to analyze the rhythmic patterns of poetry, which involves the study of the arrangement of syllables in a poetic line.
