no - it is a set boundary in the middle of the Andes.
it was the slogan used for the conflict between Canada and the U.S. "54 40" meaning the latitude lines that the countries were arguig over to set the boundaries at. The countries eventually came to the agreement to set the boundary at 49.
The "54-40 or Fight" slogan was associated with the disputed Oregon Territory boundary between the United States and British North America (Canada). The conflict was ultimately resolved through diplomacy, resulting in the border being set along the 49th parallel, which is the current boundary between the United States and Canada in that region.
I'm not aware that he did. The Adams-Onis Treaty of 1819, between the United States and Spain, gave Florida to the U.S. and set out a boundary between the U.S. and New Spain (now Mexico).
On the West, the border was set along the Appalachian Mountains; On the South, the political boundary with Spanish Florida; On the North, the political boundary with French Canada.
That is the definition of a closed set.
The set of conditions specified for the behavior of the solution to a set of differential equations at the boundary of its domain. Boundary conditions are important in determining the mathematical solutions to many physical problems.
The initial boundary was set by King George III. That boundary is (more or less) still in effect. The treaty ending the war of 1812 further clarified the border as far west as the Great Lakes. A boundary commission with international mediators set the border from Lake of the Woods to Puget Sound at 49 degrees N. Additional mediation clarified the border and divided the San Juan Islands and ensured that all portions of Vancouver Island and its close neighbors would be Canadian. The border between Alaska and Canada was moved southward along the coast from about 1898 until about 1905, when it reached its present limit.
Adams-Onis Treaty set the border between Spanish territories to the south and BC to the north, Borders were mainly set by the war of 1812 and later by Treaty of Ghent
