📖 课程概览

You will use the concept of random variables and their uses as models of uncertain future payoffs. An important concept for analysis is the conditional expectation. Special attention is given to normal distribution and multivariate normal distribution, in which explicit calculations are possible. Systems evolving in time encorporating uncertainty are modelled as stochastic (random) processes. Examples of such in discrete time are Random Walk and Martingales. As an application we look at the Risk model in insurance and obtain the bound on Ruin probability. Models in continuous time are based on Brownian motion. Stochastic analysis uses the novel concepts of Ito integral and Ito's formula. Applications in finance include the Black-Scholes model and the Ornstein-Uhlenbeck process. Simple stochastic differential equations are introduced. Another application to interest rates is Vasicek's stochastic differential equation. A new mathematical technique Change of probability measure is introduced. Girsanov theorem gives the change of measure for Brownian motion and related processes. To manage financial risks the Fundamental theorems of Asset pricing are stated and applied to various models, such as the . Binomial and Black-Scholes models. Important concepts of arbitrage, replicating portfolios are used for pricing and hedging options and other financial contracts.

📋 Workload

Three 1-hour seminars; One 2-hour applied class (in weeks 2-12) and 7 hours of independent study per week.

### 📊 课程难度与压力分析 MTH4251（Financial mathematics）属于 Monash 数学方向高阶模块，学习压力通常来自抽象概念密集、证明要求严格、题型迁移跨度大。常见失分点不是“不会某个知识点”，而是无法把定义、定理和推理步骤组织成完整答案。建议从第 1 周起建立固定闭环：每周一次概念框架梳理、一次专题题训练、一次错题复盘，把知识点沉淀为可复用模板。 ### 🎯 备考重点与高分策略高分关键是“结构化推理能力”。复习建议三轮推进：第一轮夯实定义/定理与适用条件，保证基础稳定；第二轮按题型强化（证明、计算、建模、综合应用），形成标准化步骤；第三轮限时模拟，训练符号一致性与表达完整度。证明题建议先写命题结构与关键引理，再补细节；计算/建模题先判断方法适用性与边界条件，再展开求解。 ### 📚 学习建议与资源推荐资料优先级建议：讲义与 tutorial > 作业与往年题 > 外部教材。每周至少保留 60 分钟做“错误归因”，将错误分为概念混淆、条件遗漏、步骤跳跃、计算疏漏、表达不清五类，并为每类定义下周可执行修正动作。建议持续维护“概念卡片 + 题型模板 + 错题索引”三件套。 ### ⚠️ 作业与考试避坑指南常见扣分点包括：符号未定义、逻辑跳步、边界条件缺失、只写结论不写推理、结果缺乏解释。建议按 D-7 / D-3 / D-1 节奏推进：D-7 完成主解法，D-3 做反例与边界检查，D-1 只做格式与口径核对。 ### ✅ 执行建议每周固定一次 40 分钟限时训练与 20 分钟复盘，记录“错误原因-修复动作-验证结果”。 ### 🧪 考前核对清单提交前逐项确认：是否定义符号、是否说明方法依据、是否检查边界条件、是否解释结果意义、是否完成反向验算。持续执行 8-10 周后，MTH4251 的学习稳定性与成绩通常会显著提升。建议每题最后补一行结论解释，可提升表达完整度。
