. 1. Move the cursor to the start of the text block you want to define. 2. Type M-space (the META character followed by a space). This sets a 'mark' at the start of the 'region'. 3. Move the cursor to the end of the text block you want to define as the 'region'. This sets the 'point' at the end of the 'region'. You do not have to type anything to set this 'point', the 'point' is the location of the cursor.

There are some generalizations of the classical Eisenbud-Levine-Khimshiashvili formula for the index of a singular point of an analytic vector field on $R^n$ to vector fields on singular varieties. ... For a variety with an isolated singularity, we define an index of a (real) 1-form on it. In the complex setting we define an index of a holomorphic 1-form on a complex isolated complete intersection singularity (icis) and express it as the dimension of a certain algebra. ...
