Problem 38: James' Theorem on Reflexivity
Problem Statement:
James' Theorem provides a characterization of reflexive Banach spaces.
Tasks:
a) James' Theorem Statement: State James' Theorem regarding the reflexivity of Banach spaces.
b) Proof of James' Theorem: Prove one direction of James' Theorem, showing that if a Banach space
is reflexive, then every continuous linear functional attains its supremum on the closed unit ball.
c) Implications for Optimization: Discuss how James' Theorem influences optimization problems in
reflexive Banach spaces.
d) Visualization: Illustrate a reflexive Banach space where every continuous linear functional attains
its maximum on the unit ball. Provide a graphical example in R².

- What's Neuw Discovering! This part consists of proving activities for the 6 theorems on triangle inequalities. Analyze and use the hint provided in each activity to complete the proof. Note that inequalities in triangles, even without actual measurements, can be justified deductively using theorems on inequalities in triangles. Activity 1 Directions: Complete the proof of Triangle Inequality Theorem 1(Ss→Aa) in two- column form by choosing the right statement written in the box below. Write your answer in a separate sheet of paper. PQ = PS MLPQR > MLPRQ Angle Addition Postulate Property of Inequality m22 = M2PRQ + mz3 21 = L2 m22 > M2QRP MLQSR + MZPRQ +mz3 = 180° APQS is isosceles triangle Substitution Property P. P. Given: APQR;|PR| > |PQ| Prove: mzQ > mzR R Q Proof: We cannot directly prove that mzQ > mzR, thus, there is a need to make additional constructions (see the second figure).
