هدف از این پایان نامه تعمیم قضایای بوهلر (1969)، هید (1971) و هید - براون (1971) در یک فرایند شاخه ای با محیط تصادفی است. برای فرایند شاخه ای $ lbrace z_{n} brace _ {ngeq0 } $ ، با فرض $ z_{0}=1 $ و $ m= e(z_{1}) in (0,infty) $، می دانیم $ w_{n}=z_{n}/m^{n} $ یک مارتینگل نامنفی و تقریبا مطمئن به متغیر تصادفی $ w_{infty} $ همگراست. برای نرخ همگرایی این مارتینگل، هید و بوهلر به ترتیب نتیجه گرف...
