Limits and continuity of piecewise functions. In each case, provide a specific value for a (and a specific value for b, when appropriate) to ensure that each piecewise-defined function is continuous at x=1. The " a " in one prob...
Another question is, for a fixed pair and a cross-section Σ, to determine the maximum number of center boundaries that contains Σ. The main result in the paper that answers these questions is the following. Theorem 1 Consider such that and share a focus singularity at , with the same ...
