Large N Limit of Higher Derivative Extended CP ( N ) Model
We construct a fourth-order derivative CP(N) model in 1 + 1 dimensions by incorporating the topological charge density squared term into the Lagrangian. We quantize the theory by reformulating with auxiliary fields and then performing the path integral explicitly. We discuss the renormalizability in the large N limit and relevance of the effective action with axion physics. PACS Number(s): 11.1...
متن کاملConditional Excluded Middle without the Limit Assumption
But Lewis famously objects that counterfactually supposing that a given line had been more than an inch long will not yield an A-world minimally different from i. “Just as there is no shortest possible length above 1′′,” he writes, “so there is no closest world to ours among the worlds with lines more than an inch long” (a, –; see also b, –). Lewis and Stalnaker also agree abo...
متن کاملConditional Excluded Middle without the Limit Assumption
But Lewis famously objects that counterfactually supposing that a given line had been more than an inch long will not yield an A-world minimally different from i. ‘‘Just as there is no shortest possible length above 1¢¢,’’ he writes, ‘‘so there is no closest world to ours among the worlds with lines more than an inch long’’ (1973a, 20–21; see also 1981b, 228–230). Lewis and Stalnaker also agree...
متن کاملMulti – matrix models without continuum limit
We derive the discrete linear systems associated to multi–matrix models, the corresponding discrete hierarchies and the appropriate coupling conditions. We also obtain the W 1+∞ constraints on the partition function. We then apply to multi– matrix models the technique, developed in previous papers, of extracting hierarchies of differential equations from lattice ones without passing through a c...
متن کاملConstruction of Optimal Derivative-Free Techniques without Memory
Construction of iterative processes without memory, which are both optimal according to the Kung-Traub hypothesis and derivative-free, is considered in this paper. For this reason, techniques with four and five function evaluations per iteration, which reach to the optimal orders eight and sixteen, respectively, are discussed theoretically. These schemes can be viewed as the generalizations of ...
