The singular points x = ±1 are both regular singular points. Example 6. Consider the differential equation 2x(x −2) 2 y +3xy +(x −2)y = 0. The singular points are x = 0 and x = 2; x = 0 is a regular singular point and x = 2 is an irregular singular point. ...

Einstein’s theory of general relativity predicts the existence of two irregular points where the corresponding metric blows up: the horizons and the singularities, leading to the definition of a black hole (BH). BH can be “seen” in numerous observational circumstances, including the image of ...

Some software[64,107] has facilities to set up automatically the permutation of the regular and irregular terahedra like the ones presented here by the Eq 67-71. It also modifies the name of the phases in the outputs based on the order actually calculated for the phase. Independent of the...
