In mathematics, an operator or transform is a function from one space of functions to another. Operators occur commonly in engineering, physics and mathematics. Many are integral operators and differential operators.
Mathematical Alphanumeric Symbols is a Unicode block comprising styled forms of Latin and Greek letters and decimal digits that enable mathematicians to denote different notions with different letter styles.

He was born in Chantenay-sur-Loire (today part of Nantes).He studied at École Normale Supérieure from 1926 to 1929. He received his Ph.D. in 1933. In 1934 Leray published an important paper that founded the study of weak solutions of the Navier–Stokes equations. [2]
A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula.
(exp x is also written as e x.) expi – cos + i sin function. (Also written as cis.) expm1 – exponential minus 1 function. (Also written as exp1m.) exp1m – exponential minus 1 function. (Also written as expm1.) Ext – Ext functor. ext – exterior. extr – a set of extreme points of a set.
Her books include L'enfant et les graphes (Didier, 1968), Mathématique moderne (Didier, 1970), Modern mathematics (two vols., Collier, 1968 and 1969), Graph Games (Crowell, 1971), [6] and Graphs and the Child (Harvard University Press, 1979). She also produced many educational booklets through the Belgian Center for the Pedagogy of Mathematics ...
For a lattice L in Euclidean space R n with unit covolume, i.e. vol(R n /L) = 1, let λ 1 (L) denote the least length of a nonzero element of L. Then √γ n n is the maximum of λ 1 (L) over all such lattices L. 1822 to 1901 Hafner–Sarnak–McCurley constant [118] ()
