Ħ (minuscule: ħ) is a letter of the Latin alphabet, derived from H with the addition of a bar. It is used in Maltese for a voiceless pharyngeal fricative consonant (corresponding to the letter heth of Semitic abjads: ح, ח). Lowercase ħ is used in the International Phonetic Alphabet for the same sound.
In Unicode, the special character ħ (U+210F), represents the reduced Planck constant of quantum mechanics. In this context, it is pronounced "h-bar".
The lowercase resembles the Cyrillic letter Tshe (ћ), or the astronomical symbol of Saturn (♄).
A white uppercase Ħ on a red square was the logo of Heritage Malta until 2022.
It is used as the symbol for Hedera Hashgraph's native cryptocurrency, HBAR.
As a part of WGL-4, Ħ should be displayable on most computers.

Singular cohomology is defined by dualizing the singular chain complex for spaces. We will study its basic properties, see how it acquires a multiplicative structure and becomes a graded commutative a
The student will learn state-of-the-art algorithms for solving differential equations. The analysis and implementation of these algorithms will be discussed in some detail.
H, or h, is the eighth letter in the Latin alphabet, used in the modern English alphabet, including the alphabets of other western European languages and others worldwide. Its name in English is aitch (pronounced eɪtʃ, plural aitches), or regionally haitch heɪtʃ. The original Semitic letter Heth most likely represented the voiceless pharyngeal fricative (ħ). The form of the letter probably stood for a fence or posts. The Greek Eta 'Η' in archaic Greek alphabets, before coming to represent a long vowel, /ɛː/, still represented a similar sound, the voiceless glottal fricative /h/.
