Effective Base Point Freeness on Normal Surfaces

In almost all situations, some special things are happen on a singularity. This specialty sometimes causes something unpleasant. Generally, smooth is reviewed fine and singular nasty, But in some area of geometry, it would be different. For global generations, a base locus has malignant nature, It often appears at a smooth point, at singular ’tis rare. Thus we would say “fair is foul and foul is fair” as in the classic literature, So we would “hover through the fog and filthy air” To proceed the theory with no harm And in caution against the witches charm.
