    Reversal of Osteoporosis in Lactating Female Rats by Tricalcium Phosphate (1965)

    Notes: [Auszug] We used lactating female rats so that the demand for calcium would be high, and males of the same age were used as controls. Six lactating female rats and 2 males were placed on the following diet, containing 0.04 per cent calcium: 79 per cent freshly ground yellow maize, 10 per cent dry beef ...

    Existence of solutions of games with some non-convexity (1986)

    Notes: Abstract Some inf-sup and saddle point theorems are proved for functionsf: X×Y → IR (=reals). The general theorems weaken some of the convexity conditions that are usually imposed onX, Y, andf. Some special cases are considered — these results impose some convexity in the hypotheses but still treat situations not covered by classical theorems.

    Continuous approximate solutions in parametric optimization (1989)
    Springer
    Acta applicandae mathematicae 15 (1989), S. 275-300

    Notes: Abstract The question of the existence of approximate solutions in parametric optimization is considered. Most results show that (under hypotheses) if a certain optimization problem has an approximate solution x 0 for a value p 0 of a parameter, then an approximate solution x=b(p) can be found for p in P, with b continuous, b(p 0)=x0, and any two such bs are homotopic. Some topological methods (use of fibrations) are used to weaken the usual ‘convex’ hypotheses of such results. An equisemicontinuity condition (relative to a constraint) is introduced to allow some noncompactness. The results are applied to get approximate Nash equilibrium results for games with some nonconvexity in the strategy sets.
