We propose a unified model of electromagnetism and gravitation in the framework of General Geometry. It reproduces Electromagnetism and Gravitation and predicts that electromagnetic field is a source for gravitational field. This theory is formulated in four dimensional spacetime and does not...

We find relations between quantities defining geometry and quantities defining the length of a curve in geometries underlying Electromagnetism and unified model of Electromagnetism and Gravitation. And we show that the length of a vector changes along a curve in these geometries
