Roger Apéry ( French: [apeʁi] ; 14 November 1916, Rouen – 18 December 1994, Caen ) was a French mathematician most remembered for Apéry's theorem , which states that ζ (3) is an irrational number . Here, ζ ( s ) denotes the Riemann zeta function .

He wrote his doctoral thesis in algebraic geometry under
182-593: A dynastic conflict , the war inspired French and English nationalism. The broader introduction of weapons and tactics supplanted the feudal armies where heavy cavalry had dominated, and artillery became important. The war precipitated the creation of the first standing armies in Western Europe since the Western Roman Empire and helped change their role in warfare . Civil wars, deadly epidemics, famines, and bandit free-companies of mercenaries reduced

As a result, the crown of England was held by a succession of nobles who already owned lands in France, which put them among the most influential subjects of the French king, as they could now draw upon the economic power of England to enforce their interests in the mainland. To the kings of France, this threatened their royal authority, and so they would constantly try to undermine English rule in France, while

546-751: A gradual rise in tension between the kings of France and England over territory; the official pretext was the interruption of the direct male line of the Capetian dynasty . Tensions between the French and English crowns had gone back centuries to the origins of the English royal family, which was French ( Norman , and later, Angevin ) in origin through William the Conqueror , the Norman duke who became King of England in 1066. English monarchs had, therefore, historically held titles and lands within France , which made them vassals to

However, the plan was abandoned and the fleet, including elements of the Scottish navy, moved to the English Channel off Normandy in 1336, threatening England.

Rouen did not go quietly: Alain Blanchard hanged English prisoners from the walls, for which he was summarily executed after the city surrendered, while Canon and Vicar General of Rouen Robert de Livet became a hero for excommunicating the English king, resulting in de Livet's imprisonment for five years in England. Joan of Arc , who supported a return to French rule,

Therefore, excluding Edward, the nearest heir through the male line was Charles IV's first cousin, Philip, Count of Valois , and it was decided that he should take the throne. He was crowned Philip VI in 1328. In 1340, the Avignon papacy confirmed that, under Salic law , males would not be able to inherit through their mothers. Eventually, Edward III reluctantly recognized Philip VI and paid him homage for

The dispute over Guyenne is even more important than the dynastic question in explaining the outbreak of the war.

England permanently lost most of its continental possessions, with only the Pale of Calais remaining under its control on the continent until the Siege of Calais (1558). Local conflicts in neighbouring areas, which were contemporarily related to

2912-502: The Burgundians raised the prospects of an ultimate English triumph and persuaded the English to continue the war over many decades. A variety of factors prevented this, however. Notable influences include the deaths of both Henry and Charles in 1422, the emergence of Joan of Arc (which boosted French morale), and the loss of Burgundy as an ally (concluding the French civil war). The Siege of Orléans (1429) made English aspirations for conquest all but infeasible. Despite Joan's capture by

However, at the ceremony, Philip VI had it recorded that the homage was not due to the fiefs detached from the duchy of Guyenne by Charles IV (especially Agen). For Edward, the homage did not imply the renunciation of his claim to the extorted lands. In the 11th century, Gascony in southwest France had been incorporated into Aquitaine (also known as Guyenne or Guienne ) and formed with it
3458-498: The French forces under the House of Valois ultimately retained control over the Kingdom of France. The French and English monarchies thereafter remained separate, despite the monarchs of England (later Britain ) styling themselves as sovereigns of France until 1802 . The root causes of the conflict can be traced to the crisis of 14th-century Europe . The outbreak of war was motivated by

An assembly of French barons decided that a native Frenchman should receive the crown, rather than Edward. The throne passed to Charles's patrilineal cousin instead, Philip , Count of Valois . Edward protested but ultimately submitted and did homage for Gascony. Further French disagreements with Edward induced Philip, during May 1337, to meet with his Great Council in Paris. It

In return for increased lands in Aquitaine, Edward renounced Normandy, Touraine, Anjou and Maine and consented to reduce King John's ransom by a million crowns. Edward also abandoned his claim to the crown of France. The French king, John II , was held captive in England for four years. The Treaty of Brétigny set his ransom at 3 million crowns and allowed for hostages to be held in lieu of John. The hostages included two of his sons, several princes and nobles, four inhabitants of Paris, and two citizens from each of

Therefore, sovereignty over Guyenne was a latent conflict between the two monarchies for several generations. During
