"Truth" and Solving Problem(s) 
  Math. Forum: These disguised topics were inspired by other topics recently posted in Math Forum: Truth - Symbols and Definitions: Truth takes form (Human Form) with some sort of symbolic representation and some form of their definition. Like Mathematics! Symbols could include Thoughts, Language, behavior (external/internal; Mental/Physical), Math. Language; which can be shown to represent some existential phenomena.... more »

Question in Hypergraph theory: How many edges of t-uniform h.g. are needed such that every s-subset (s<=t) is a shadow induced by this h.g.? 
  Hello, does anyone of you know whether there are answers in the published literature to the following question: Let n be a positive integer. Fix integers 1 <= t <= n and 1 <= s <= t. What is the minimum number of t-element subsets of the set {1,...,n} such that every s-element subset of {1,...,n} is contained in... more »

recursive functions from N->N with fast growth 
  The following question occurred to me while thinking about some things I wrote in the thread "computable reals (beta version)": Does there exist a recursive function f: N->N such that for every recursive function g: N->N that eventually strictly dominates f, and every two-symbol Turing machine M that computes g by returning... more »
