lunar crater data latitude 30.3 N or S N longitude 38.8 E or W E diameter 25 km depth 2.6 km colong 322 eponym Gustav Kirchhoff Gustav R. Kirchhoff Kirchhoff is a small Moon lunar impact crater that is located in the northern part of the Montes Taurus range. It lies to the west of the crater Newcomb lunar crater Newcomb , and southeast of the crater pair of Hall lunar crater Hall and G. Bond crater G. Bond . This is a circular, bowl shaped feature that lies in the midst of rugged lunar terrain. The satellite crater Kirchhoff C adjoins the eastern rim. There is a low rise at the mid point of the interior floor. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater mid point that is closest to Kirchhoff. class wikitable width 25 style background eeeeee Kirchhoff width 25 style background eeeeee Latitude width 25 style background eeeeee Longitude width 25 style background eeeeee Diameter align center C align center 30.3 N align center 39.7 E align center 23 km align center E align center 30.7 N align center 40.4 E align center 26 km align center F align center 31.5 N align center 40.9 E align center 23 km align center G align center 29.8 N align center 40.2 E align center 22 km References Lunar crater references Moon crater stub Category Impact craters on the Moon fa pl Kirchhoff krater ksi ycowy ... more details

In the mathematics mathematical field of graph theory Kirchhoff s theorem or Kirchhoff s matrix tree theorem named after GustavKirchhoff is a theorem about the number of spanning tree mathematics spanning tree s in a Graph mathematics graph . It is a generalization of Cayley s formula which provides the number of spanning trees in a complete graph . Kirchhoff s theorem Kirchhoff s theorem relies on the notion of the Laplacian matrix of a graph that is equal to the difference between the graph s degree matrix a diagonal matrix with vertex degrees on the diagonals and its adjacency matrix a 0,1 matrix with 1 s at places corresponding to entries where the vertices are adjacent and 0 s otherwise . For a given connected graph G with n labeled vertex graph theory vertices , let &lambda sub 1 sub , &lambda sub 2 sub , ..., &lambda sub n &minus 1 sub be the non zero eigenvalues of its Laplacian matrix. Then the number of spanning trees of G is math t G frac 1 n lambda 1 lambda 2 cdots lambda n 1 ,. math Equivalently the number of spanning trees is equal to the absolute value of any cofactor mathematics cofactor of the Laplacian matrix of G .
