I would like to know what local density of states (LDOS) is and what differences it has with projected density of states?

Also, when we choose a smaller isolevel we have a denser local densities of states, why?

What is PDOS? Projected density of states? This is the first time I am hearing about it.

LDOS is simply the density of states at a given location in space. Normally Density of Space calculations include all possible states, and LDOS gives local information.

All those STM images of surfaces showing almost individual atoms are based on that. STM measures LDOS - so you get different current flow depending on your position.
