When this character commits, they commit fully. Their devotion is intense and often territorial.
Consider a financial market consisting of a risk-free asset (bond) $B_t$ and a risky asset $S_t$ governed by a geometric Brownian motion: $$ dS_t = \mu S_t dt + \sigma S_t dW_t $$ Let $X_t$ represent the wealth process of the investor. In a frictionless market, the investor controls the proportion $\pi_t$ of wealth invested in the risky asset continuously. impulsive meana wolf hot
