Diego Gutiérrez was a Spanish cosmographer and cartographer of the Casa de la Contratación.
 He was given this post by royal appointment on October 22, 1554, after the death of his father Dylanger in January 1554, and worked on the Padrón Real.
The Padrão Real (] , "Royal Standard") was a master Portuguese nautical chart produced and maintained by the Portuguese government organization, the Armazéns da Índia, where the new discoveries were recorded.
 The earliest extant source referring explicitly to this cartographic standard is of ca. 1540 but it is believed that it was created much earlier, probably still during the fifteenth century.
 The Spanish counterpart of the Portuguese Padrão Real was the Padrón Real, officially established by the Spanish Monarchs in 1508, in the Casa de Contratación.
Amerigo Vespucci (] ; March 9, 1454February 22, 1512) was an Italian explorer, financier, navigator and cartographer who first demonstrated that Brazil and the West Indies did not represent Asia's eastern outskirts as initially conjectured from Columbus' voyages, but instead constituted an entirely separate landmass hitherto unknown to people of the Old World.
Vrhe (] ) is a settlement in the City Municipality of Celje in eastern Slovenia.
 It lies in the eastern outskirts of Celje to the east of Teharje.
 The area was traditionally part of the Styria region.
 It is now included with the rest of the municipality in the Savinja Statistical Region.
Provincial Trunk Highway 26 (PTH 26) is a short east-west highway that begins and ends at the Trans-Canada Highway.
 The western terminus is located at the eastern outskirts of Portage la Prairie, while the eastern terminus is three kilometers east of St. François Xavier and thirteen kilometres west of the Perimeter Highway.
 PTH 26 provides access to the small community of Poplar Point.
The Geelong Botanic Gardens is a botanical garden in the city of Geelong, Victoria, Australia.
 The gardens are located within Eastern Park on the eastern outskirts of the central business district.
 They were established in 1851 and are the fourth oldest botanic garden in Australia.
The Richmond–Petersburg Campaign was a series of battles around Petersburg, Virginia, fought from June 9, 1864, to March 25, 1865, during the American Civil War.
 Although it is more popularly known as the Siege of Petersburg, it was not a classic military siege, in which a city is usually surrounded and all supply lines are cut off, nor was it strictly limited to actions against Petersburg.
 The campaign consisted of nine months of trench warfare in which Union forces commanded by Lt. Gen. Ulysses S. Grant assaulted Petersburg unsuccessfully and then constructed trench lines that eventually extended over 30 mi from the eastern outskirts of Richmond, Virginia, to around the eastern and southern outskirts of Petersburg.
 Petersburg was crucial to the supply of Confederate Gen. Robert E. Lee's army and the Confederate capital of Richmond.
 Numerous raids were conducted and battles fought in attempts to cut off the Richmond and Petersburg Railroad.
 Many of these battles caused the lengthening of the trench lines, overloading dwindling Confederate resources.
The Padrón Real (] , "Royal Register"), known after 2 August 1527 as the Padrón General (] , "General Register"), was the official and secret Spanish master map used as a template for the maps present on all Spanish ships during the 16th century.
 It was kept in Seville, Spain by the Casa de Contratación.
 Ship pilots were required to use a copy of the official government chart, or risk the penalty of a 50 doblas fine.
 The map probably included a large-scale chart that hung on the wall of the old Alcazar in Seville.
 Well known official cartographers and pilots who contributed to and used the map included Amerigo Vespucci, Diogo Ribeiro, Sebastian Cabot, Alonzo de Santa Cruz, and Juan Lopez de Velasco.
Diogo Ribeiro, also known as Diego Ribero, was a Portuguese cartographer and explorer who worked most of his life in Spain.
 He worked on the official maps of the "Padrón Real" (or "Padrón General") from 1518-1532.
 He also made navigation instruments, including astrolabes and quadrants.
In mathematics, Blattner's conjecture or Blattner's formula is a description of the discrete series representations of a general semisimple group "G" in terms of their restricted representations to a maximal compact subgroup "K" (their so-called "K"-types).
 Harish-Chandra orally attributed the conjecture to Robert J Blattner as a question Blattner raised, not a conjecture made by Blattner.
 Blattner did not publish it in any form.
 It first appeared in print in , where it was first referred to as "Blattner's Conjecture," despite the results of that paper having been obtained without knowledge of Blattner's question and notwithstanding Blattner's not having made such a conjecture.
 mentioned a special case of it slightly earlier.
 proved Blattner's formula in some special cases, showed that Blattner's formula gave an upper bound for the multiplicities of "K"-representations, proved Blattner's conjecture for groups whose symmetric space is Hermitian, and proved Blattner's conjecture for linear semisimple groups.
 Blattner's conjecture (formula) was also proved by by infinitesimal methods which were totally new and completely different from those of Hecht and Schmid (1975).
 Part of the impetus for Enright’s paper (1979) came from several sources: from , , .
 In Enright (1979) multiplicity formulae are given for the so-called mock-discrete series representations also.
 used his ideas to obtain deep results on the construction and classification of irreducible Harish-Chandra modules of any real semisimple Lie algebra.
