in his recognition of being and achievement of truth, man has two instruments in his constitution and two ways before him: intellect and heart; reasoning and intuition. some have opted the way of reasoning and underestimated intuition because of its lack of reasoning, and some have preferred intuition over reasoning because of its being presential (intuitive). with their research on philosophy ...

This paper investigates the existence of absolute optimal solutions for a partition P in continuous and quasiconcave games. We show that the P -consistence property introduced in the paper, together with the quasiconcavity and continuity of payoffs, permits the existence of P -absolute optimal solutions in games with compact and convex strategy spaces. The P consistency property is a general co...

this paper tries to describe the way jaspers understands the term ‘existence’. according to jaspers ‘existence is ’ indefinable. if so, how then can it be expressed? not by concepts,but by what jaspers calls ‘signa’. the terms such as ‘existence’, ‘freedom’ and ‘selfhood’ are examples of such ‘signa’. however, ‘signa’ per se have no objectivity for consciousness, no independent meaning. from th...

We construct an index theorem for smooth infinite economies that shows that generically the number of equilibria is odd. As a corollary, this gives a new proof of existence and gives conditions that guarantee global uniqueness of equilibria.

We present a simple proof of existence of subgame perfect equilibria in games with perfect information.

Lévy driven term structure models have become an important subject in the mathematical finance literature. This paper provides a comprehensive analysis of the Lévy driven Heath–Jarrow–Morton type term structure equation. This includes a full proof of existence and uniqueness in particular, which seems to have been lacking in the finance literature so far.
