Rom 102 to 103 proteins in bacteria and from 103 to 104 proteins in eukaryotes). The protein database (or PDB) includes about 1.eight 105 entries [4]. Proteins make sure the language of life, amino acids will be the alphabet, proteins are the words as well as the set of proteins in an organism will be the phrases. Analogously in music, a note is a letter encoding a musical sound. In the 12-tone chromatic scale [5], each of your 12 notes (or letters) has the frequency from the earlier notePublisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations.Copyright: 2021 by the authors.

The form refers to the secondary structure of a musical composition when it comes to clear-cut units of equal length, for example, A-B-A within the sonata form or A-B-C-B-A in an arch type [6]. Now, we come to human language as well as the Latin alphabet. You’ll find 26 letters organized into words of a variety of forms like names, adjectives, verbs, and so on. Within the following, we’ll show that a verse inside a poem or a phrase in prose have distinctive options, the former becoming closer to our theory. Our mathematical theory on the secondary structures in proteins, music and poems relies on the concept of a finitely generated group along with the corresponding graph coverings, as explained in Section two. We’ll investigate three applications of the graph covering approach. In Section 3, we look in the secondary structures of two proteins. We take as examples the spike protein of the SARS-Cov-2 virus along with a glycoprotein playing a function in the immune system (see [3] for our earlier function). In Section 4, the secondary structures are the musical forms of western music within the classical age and twentieth century music. Then, in Section 5, the secondary structures inside the verses of chosen poems are obtained from an encoding from the types of words (names, verbs, prepositions, and so on). A Brief Review in the Literature Soon after we received an invitation to contribute to the present special challenge of Sci “mathematics and poetry, using a view towards machine learning” we believed that our existing group theoretical strategy of protein language [3] could possibly be converted into an understanding with the poetic language, also as an understanding of some musical structures. Our target in this subsection is always to point out earlier work in the same direction as ours. There are numerous papers attempting to PF-05105679 In Vivo relate group theory for the genetic code, as reviewed in [2] but we discovered none of them ML-SA1 In Vitro featuring the secondary structure of proteins along the chain of amino acids, as we did in [3] and as we do under together with the graph coverings. Poetry inspired mathematics has been the prevalent thread of most papers exploring the connection involving poems and maths [70]. Nevertheless, it’s additional difficult to clarify what sort of structure and beauty occurs inside a poem inside the language of mathematics [11]. Possibly mathematical linguistics would be the proper frame for making progress [12] and artificial intelligence (AI) may perhaps support within the classification of languages [13]. Though both subjects happen to be connected for centuries, comparing musical structures to mathematics is really a fairly new study do.
