The Order of Saint Lazarus of Jerusalem was a Roman Catholic military order founded by crusaders around 1119 at a leper hospital in Jerusalem, Kingdom of Jerusalem, whose care became its original purpose, named after patron saint Lazarus. It was recognised by King Fulk of Jerusalem in 1142 and canonically recognised as hospitaller and military order of chivalry under the rule of Saint Augustine in the Papal bull Cum a Nobis Petitur of Pope Alexander IV in 1255. The titular seat was successively situated at Jerusalem, Saint-Jean-d'Acre and - after the fall of the Kingdom of Jerusalem - the Château Royal de Boigny-sur-Bionne in France. After several centuries, the order went into decline and ceased to perform its original functions after the French Revolution.
In 1489, Pope Innocent VIII attempted to merge the order and its land holdings with the Sovereign Military Order of Malta. This was resisted by the order in most countries where it still retained its premises.
In 1572, the Order of Saint Lazarus in Italy was merged with the Order of Saint Maurice under the Royal House of Savoy to form the Order of Saints Maurice and Lazarus, which still exists until today.
The Military and Hospitaller Order of Saint Lazarus of Jerusalem (Latin: Ordo Militaris et Hospitalis Sancti Lazari Hierosolymitani) is a Christian ecumenical lay order statuted in 1910 by a council of Catholics in Paris, France, initially under protection of Patriarch Cyril VIII Jaha of the Melkite Greek Catholic Church. Its purpose is "care and assistance of the sick and the poor, and to the support and defense of the Christian faith and the traditions and principles of Christian chivalry." Some 5,000 members are divided under three grand magistries with controversial historical claims, yet carrying out "praiseworthy charitable, humanitarian activity."
Despite pretenses of dynastic legacy recognised by individual ecclesial and royal dignitaries, attributions to the medieval Catholic military order of the Order of Saint Lazarus, founded in 1119, are not recognised by the Holy See, or other souvereign heads of state, neither by the International Commission on Orders of Chivalry, thus widely considered a self-styled order.
The Order of Saint Lazarus was a Roman Catholic military order founded around 1119 by crusaders in the Latin Kingdom of Jerusalem.

In mathematics, big O notation describes the limiting behavior of a function when the argument tends towards a particular value or infinity, usually in terms of simpler functions. It is a member of a larger family of notations that is called Landau notation, Bachmann–Landau notation (after Edmund Landau and Paul Bachmann), or asymptotic notation. In computer science, big O notation is used to classify algorithms by how they respond (e.g., in their processing time or working space requirements) to changes in input size. In analytic number theory, it is used to estimate the "error committed" while replacing the asymptotic size, or asymptotic mean size, of an arithmetical function, by the value, or mean value, it takes at a large finite argument. A famous example is the problem of estimating the remainder term in the prime number theorem.
Big O notation characterizes functions according to their growth rates: different functions with the same growth rate may be represented using the same O notation.
