Game theory equilibrium concepts

Epsilon-equilibrium

In game theory, an epsilon-equilibrium, or near-Nash equilibrium, is a strategy profile that approximatelysatisfies the condition of Nash equilibrium. In a Nash equilibrium, no player has an incentive to change hisbehavior. In an approximate Nash equilibrium, this requirement is weakened to allow the possibility that aplayer may have a small incentive to do something different. This may still be considered an adequatesolution concept, assuming for example status quo bias. This solution concept may be preferred to Nashequilibrium due to being easier to compute, or alternatively due to the possibility that in games of morethan 2 players, the probabilities involved in an exact Nash equilibrium need not be rational numbers.

Epsilon delta limit (Example 3): Infinite limit at a point

This is the continuation of the epsilon-delta series! You can find Examples 1 and 2 on blackpenredpen's channel. Here I use an epsilon-delta argument to calculate an infinite limit, and at the same time I'm showing you how to calculate a right-hand-side limit. Enjoy!

ultimate introduction to the epsilon-delta definition of a limit

My most detailed introduction to the epsilon-delta definition of limits in calculus! The epsilon-delta definition of a limit is commonly considered the hardest topic in calculus 1 (it's also the important part at the beginning of real analysis). The best way to understand this precise defi

In this video we aim to give a precise and simpler definition for what it means to say that: a rational polynumber on-sequence p(n) has a limit A, for some rational number A. Our definition is both much simpler and more logical than the usual epsilon -delta definition found in calculus tex
