In number theory, Cramér's conjecture, formulated by the Swedish mathematician Harald Cramér in 1936, is an estimate for the size of gaps between consecutive prime numbers: intuitively, that gaps between consecutive primes are always small, and the conjecture quantifies asymptotically just how small they can be.

In estimation theory and statistics, the Cramér – Rao bound ( CRB ) or Cramér – Rao lower bound ( CRLB ), named in honor of Harald Cramér and Calyampudi Radhakrishna Rao who were among the first to derive it, expresses a lower bound on the variance of estimators of a deterministic parameter.

The Swedish mathematician Harald Cramér met Lindeberg in 1922.

Harald was married to Ingrid Ragnvaldsdottir, daughter of Ragnvald Ingesson, the son and heir of King Inge I of Sweden.

According to the sagas, Harald had previously been married to Bjadok.

On 21 March 1929 in Oslo, he married his first cousin Princess Märtha of Sweden with whom he had one son, Harald, and two daughters, Ragnhild and Astrid.

The possibility that Harald had married a Danish princess may find some support in a skaldic stanza which is usually assigned to Þorbjörn Hornklofi's Hrafnsmál, a eulogy on Harald's deeds in the form of a conversation between a raven and valkyrie.

After being queen for a while, Gurid married one of Borgar's sons, Halfdan, and they had a son named Harald, who became the new king of Denmark.

Widowed in 1246, she married Harald Olafsson, King of Mann and the Isles in 1248.

He is married to Bjørg Bondevik ( née Rasmussen ), and has the three children Bjørn ( born 1972 ), Hildegunn ( born 1973 ) and John Harald ( born 1976 ).

He is recorded as the child of Tora Torbergsdatter, who married Harald in 1048.

This second Halfdan the Old is father of Jarl Ívar of the Uplands who married a daughter of a certain Eistein and so became father of Eystein the Clatterer ( Eysteinn Glumra ) who was father of Jarl Rögnvald of Møre and of Rögnvald's brother Sigurd Eysteinsson, and also of two daughters: Svanhild who was one of King Harald Fairhair's wives and another daughter named Malahule.

He was married three times, and fathered 20 children or more, including the five future kings Harald III Hen, Canute IV the Saint, Oluf I Hunger, Eric I Evergood and Niels out of wedlock.

After Harald Hardrada's death, Sweyn married his widow Tora Torbergsdatter.

" Grundy contrasts this with accounts of polygynous marriages among the Merovingians and Carolingians, points out that the only Germanic law-code that expressly forbids such relationships is that of the Visigoths, and notes that while polygynous marriages are rarely attested in Scandinavian sources, Harald I of Norway was married to seven wives simultaneously.

Magnus ' illegitimate daughter Ragnhild Magnusdotter married Harald Kesja, an illegitimate son of Eric I of Denmark.

One would interpret the saga account of Sigrid as a confused rendering of a princess, ' Świętosława, daughter of first duke of the Polans Mieszko I, who married in succession Erik and Swein, being mother of Olaf ( by Erik ), Harald and Cnut ( both by Swein ).

The following year, Auðr went to Garðaríki with her son Harald and many powerful men and married its king Ráðbarðr.
