Abstract:  The connection between the BDDC (Balancing Domain
           Decomposition by Constraints) algorithm and the FETI-DP
           (Finite Element Tearing and Interconnecting Dual-Primal)
           algorithm is discussed in the language of function spaces,
           operators and linear functionals.
