def task_func(LETTERS=[chr(i) for i in range(97, 123)]):
    """
    Create a dictionary where keys are letters from a predefined list LETTERS and values are lists of random integers.
    Then, calculates the population standard deviation for each list of integers and returns a dictionary of these values.

    The random integers for each key are generated within the range 0 to 100, and each list contains between 1 to 10 integers.

    Parameters:
        LETTERS (list of str, optional): A list of single-character strings to be used as keys in the output dictionary.
                                         Defaults to the lowercase English alphabets ['a', 'b', ..., 'z'].

    Returns:
        dict: A dictionary where each key corresponds to a letter from the input list and each value is the 
              population standard deviation of a list of random integers associated with that key.

    Requirements:
    - random
    - math

    Example:
    >>> import random
    >>> random.seed(42)
    >>> sd_dict = task_func()
    >>> print(sd_dict)

Create a dictionary where keys are letters from a predefined list LETTERS and values are lists of random integers. Then, calculates the population standard deviation for each list of integers and returns a dictionary of these values. The random integers for each key are generated within the range 0 to 100, and each list contains between 1 to 10 integers.
The function should output with:
    dict: A dictionary where each key corresponds to a letter from the input list and each value is the
    population standard deviation of a list of random integers associated with that key.
You should write self-contained code starting with:
