The Persian alphabet (Alefbâye Fârsi), also known as the Perso-Arabic script, is the right-to-left alphabet used for the Persian language. It is a variation of the Arabic alphabet with four additional letters added: پ چ ژ گ. It was the basis of many Arabic-based scripts used in Central and South Asia. It is used for the Iranian and Dari standard varieties of Persian; and is one of two official writing systems for the Persian language, alongside the Cyrillic-based Tajik alphabet.
The script is mostly but not exclusively right-to-left; mathematical expressions, numeric dates and numbers bearing units are embedded from left to right. The script is cursive, meaning most letters in a word connect to each other; when they are typed, contemporary word processors automatically join adjacent letter forms.
The Persian alphabet is directly derived and developed from the Arabic alphabet. The Arabic Alphabet was introduced to the Persian-speaking world after the Muslim conquest of Persia and the fall of the Sasanian Empire in the 7th century. Following which, the Arabic language became the principal language of government and religious institutions in Persia, which led to the widespread usage of the Arabic script. Classical Persian literature and Poetry were affected by this simultaneous usage of Arabic and Persian. A new influx of Arabic vocabulary soon entered the Persian language. In the 8th century the Tahirid dynasty and Samanid dynasty officially adopted the Arabic script for writing Persian, followed by the Saffarid dynasty in the 9th century, gradually displacing the various Pahlavi scripts used for the Persian language prior. By the 9th-century the Perso-Arabic alphabet became the dominant form of writing in Greater Khorasan.
Under the influence of various Persian Empires, many languages in Central and South Asia that adopted the Arabic script use the Persian Alphabet as the basis of their writing systems. Today, extended versions of the Persian alphabet are used to write a wide variety of Indo-Iranian languages, including Kurdish, Balochi, Pashto, Urdu (from Classical Hindostani), Saraiki, Panjabi, Sindhi and Kashmiri.

The Arabic script is the writing system used for Arabic and several other languages of Asia and Africa. It is the second-most widely used alphabetic writing system in the world (after the Latin alphabet), the second-most widely used writing system in the world by number of countries using it or a script directly derived from it, and the third-most by number of users (after the Latin and Chinese scripts). The script was first used to write texts in Arabic, most notably the Quran, the holy book of Islam.
Shahmukhi (, ਸ਼ਾਹਮੁਖੀ) is an Abjad developed from the Perso-Arabic alphabet script, used for the Punjabi language. It came into use in Punjabi Sufi literature, from the 12th century and onwards. It is generally written in the Nastaʿlīq calligraphic hand, which is also used for Urdu. Shahmukhi script is the standard script in Pakistani Punjab used for Punjabi. Perso-Arabic is one of two scripts used for Punjabi, the other being Gurmukhi used in the Indian Punjab. Shahmukhi is written from right to left, while Gurmukhi is written from left to right.
Dari (ˈdɑːri,_ˈdæ-; endonym: دری d̪ɐˈɾiː), also known as Dari Persian (Dari: فارسی دری, , fʌːɾˈsiːjɪ d̪ɐˈɾiː or , fʌːɾˈsiːjɛ d̪ɐˈɾiː), is the variety of the Persian language spoken in Afghanistan. Dari is the term officially recognised and promoted since 1964 by the Afghan government for the Persian language; it is known as Afghan Persian or Eastern Persian in many Western sources. As Professor Nile Green remarks, "the impulses behind renaming of Afghan Persian as Dari were more nationalistic than linguistic" in order to create an Afghan state narrative.
Balanced bipolar codes consist of sequences in which the symbols ‘−1’ and ‘+1’ appear equally often. Several generalizations to larger alphabets have been considered in literature. For example, for the q-ary alphabet {−q+1,−q+3, . . . , q−1}, known concept ...

We consider a very simple Mealy machine ( two nontrivial states over a two-symbol alphabet), and derive some properties of the semigroup it generates. It is an infinite, finitely generated semigroup, and we show that the growth function of its balls behave ...
