((a)) Trustees, receivers or managers of any property, including debtors in possession, may be sued, without leave of the court appointing them, with respect to any of their acts or transactions in carrying on business connected with such property. Such actions shall be subject to the general equity power of such court so far as the same may be necessary to the ends of justice, but this shall not deprive a litigant of his right to trial by jury.
((b)) Except as provided in , a trustee, receiver or manager appointed in any cause pending in any court of the United States, including a debtor in possession, shall manage and operate the property in his possession as such trustee, receiver or manager according to the requirements of the valid laws of the State in which such property is situated, in the same manner that the owner or possessor thereof would be bound to do if in possession thereof.
